Key benefits
  • Anti-inflammatory
  • Carminative
  • Anti-microbial
  • Galactagogue
  • How does it feel?

    Saffron increases one’s sense of physical and psychological wellbeing. When the circulation and blood quality is improved, increased energy and nutrition is delivered to the cells, enhancing the health status and function in all of the systems of the body.

    Saffron is mildly bitter, with a sweet and warming energy. In Ayurveda, saffron treats conditions of excess Vata (in simple terms, vata, is the humour of air and space that creates dry and cold conditions). A Sattvic herb; whose actions on the blood bring about feelings love and compassion.

  • What can I use it for?

    Saffron is one of the more expensive herbs in the Materia Medica, so may not be the best ‘go-to’ for acute conditions where a more accessible option could be available. However, it presents a unique balance of properties that can make it a desirable  herb of choice to support during times of emotional fragility.

    Saffron supports the nervous system, which includes the peripheral nerves and the brain.

    It can be helpful to use where issues in the menstrual cycle present with symptoms of menstrual pain, headaches and low mood due to its antidepressant, mood elevating properties.

    It can also be a herb of choice incorporated into culinary recipes for digestive support or to increase assimilation and absorption of nutrients from the diet.

  • Into the heart of saffron

    Energetically, saffron gives a glow of love and warmth. Like any herb that supports the circulation and the nervous system, saffron increases mental wellbeing by nourishing the nerves and increasing the movement of blood and energy in the tissues.

    In Ayurveda, saffron is described as Sattvic (a quality of lovingness and compassion, reflected in nature), giving the nurturing energy of love. It would therefore be indicated for those experiencing grief or other emotional pain, possibly accompanied by a depressed emotional state.

    Saffron supports and uplifts with its gentle nurturing energy, whilst supporting the physical systems most effected by this condition.

    Described as one of the best aphrodisiac herbs, saffron improves libido, raises feelings of love and sensuality. Saffron improves the circulation to the reproductive organs making it a wonderful tonic herb for both men and women.

  • Traditional uses

    The use of saffron in treatment of mood disorders such as depression has a long tradition, ranging from antiquity to modern times. It is long believed that Saffron may have a modulating effect on certain chemicals in the brain, including serotonin which is fundamental for good mental health (8).

    Saffron has also a long standing history of use for digestive issues, with its carminative action and ability to support digestion (9).

    Traditionally Saffron was indicated for treatment of measles, as a diaphoretic herb (a herb that induces sweating) (9). It may have been used to support the important immunological process of a viral fever. It was also traditionally used in the prevention of complications associated with the pox’s (smallpox and chickenpox) such as retrocession of the classic rash that in some cases infects the nerves and visceral organs, rather than coming out through the skin. One of the old treatments for this was saffron as a circulatory stimulant. It was believed to help bring out the rash and protect the nerves (10).

  • Traditional actions

    Herbal actions describe therapeutic changes that occur in the body in response to taking a herb. These actions are used to express how a herb physiologically influences cells, tissues, organs or systems. Clinical observations are traditionally what have defined these actions: an increase in urine output, diuretic; improved wound healing, vulnerary; or a reduction in fever, antipyretic. These descriptors too have become a means to group herbs by their effects on the body — herbs with a nervine action have become the nervines, herbs with a bitter action are the bitters. Recognising herbs as members of these groups provides a preliminary familiarity with their mechanisms from which to then develop an understanding of their affinities and nuance and discern their clinical significance.

  • Traditional energetic actions

    Herbal energetics are the descriptions Herbalists have given to plants, mushrooms, lichens, foods, and some minerals based on the direct experience of how they taste, feel, and work in the body. All traditional health systems use these principles to explain how the environment we live in and absorb, impacts our health. Find out more about traditional energetic actions in our article “An introduction to herbal energetics“.

  • What practitioners say

    In creating a balanced prescription of multiple herbs, a herbalist will often use an aromatic herb to harmonise a blend. Aromatic herbs, such as Saffron, increase the digestive fire, improving assimilation and absorption of nutrients and medicinal compounds whilst assisting to deliver them to the tissues that need them.

    Aromatic herbs are also often nervine (nourishing or benefitting the nervous system) and as they often have a pleasing taste, they tend to tie herbal formulations together. This adds a final harmonizing note to a prescription, forging the unique quality of herbal medicines that they can engage all the senses of the patient.

    As an expensive but also extremely potent herb, saffron will most often be used in subtle or lower quantities as part of a prescription.

    Saffron is used by Western herbalists to treat a number of conditions associated with the nervous and cardiovascular systems, as well as to support those suffering with depression.

    Like other herbs that contain high levels of volatile oils (aromatic compounds), saffron is described in Ayurvedic tradition as a herb that is supportive for the digestive fire. As with many aromatic plants, saffron will offer increased digestive function, also improving the assimilation of nutrients from the diet (1,2).

    It is indicated where general tissue state is diminished, in conditions whose characteristics are dry and cold. In terms of tissue types that saffron supports, this would be epithelial and nervous tissue specifically.

    A classic presentation for this dry and cold pattern of illness would present with pallid complexion, heightened sense of coldness, slow movement, decreased intensity of sensation. Fatigue and difficulty thinking clearly. Pale tongue or bluish and slow pulse. Achy, dull pain that feels better with heat or warming herbs. Food stagnation, flatulence, bloating and belching may occur as a result of reduced digestive fire. The underlying cold would need to be treated with warming, stimulating herbs such as saffron.

    It is thought to be one of the best herbs for liver – spleen regulation, and for generally supporting metabolism. A herb that supports the actions of other herbs through increased assimilation and movement into the tissues of the body (1).

    In the Traditional Western practice, in order to identify the status of tissue health (namely epithelial tissue/ mucous membranes – that which lines the inner surface of most internal organs and orifices) a herbalist will visually observe the tongue, inner eyelids combined with an in depth analysis of physical health under consultation. Observing the overall tissue state of the person as well as any local and obvious anomalies can greatly enhance a herbalist’s ability to identify the nature of an ailment and treatment approaches. Saffron would be best applied where there is atrophy or weakness in the tissues of the nervous system or where the epithelial tissue is under stimulated and cellular health is diminished.

  • Research

    Type 2 diabetes

    Diabetes is characterized by high blood sugar, which can lead to chronic damage to the heart, nerves and blood vessels. Research shows that saffron can reduce diabetic complications, for example it can reduce fasting plasma glucose levels and can significantly reduce waist circumference (15).

    Depression

    In a double-blind, placebo-controlled, single-centre and randomized trial, patients were randomly assigned to receive a capsule of dried saffron 30 mg a day or a placebo capsule for the duration of a 6-week study. At 6 weeks, Crocus sativus produced a significantly better outcome on the Hamilton depression rating scale than the placebo. The results of this study indicate the efficacy of Crocus sativus in the treatment of mild to moderate depression (12).

    In another double-blind, single-centre trial and randomized trial, patients were randomly assigned to receive capsules of saffron 30 mg/day (BD) and capsule of fluoxetine (an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class) at 20 mg/day for a 6-week study. At this dose, Saffron was found to be almost equally as effective as fluoxetine in the treatment of mild to moderate depression. The results of this study indicate the efficacy of Crocus sativus in the treatment of mild to moderate depression. Saffron effects serotonin levels, and so this is one of the ways it can affect mood. The aqueous extract of saffron increases brain dopamine, as well as glutamate concentrations (17).

    Nervous system

    A nourishing nervine herb, saffron has a direct action upon the nervous system. This can be applied as part of a supportive approach for conditions of the mind, such as anxiety, depression and nervous debility. It is a plant that has uplifting and mood enhancing qualities (1,11,12).

    Because saffron improves blood flow to the brain and peripheral nerves, saffron is also indicated for degenerative and debilitating diseases associated with the nervous system such as Alzheimer’s and dementia (18,19). 2 separate clinical trials were conducted on patients with mild to moderate Alzheimer’s disease (18,19). The efficacy of treatment was evaluated using the AD Assessment Scale and cognitive subscale, as well as the Clinical Dementia Rating Scale. The research shows that saffron produced a significantly superior outcome on cognitive function when compared to placebo. The effectiveness of improving cognition was equal to that of the pharmaceutical donepezil. Both decreased the score in Clinical Dementia Rating Scale by 0.7-0.8, and the Alzheimer’s Disease Assessment Scale by 3.7 (18,19).

    In Ayurveda, saffron is also used to treat headaches, such as tension headaches likely ones caused by stress and anxiety this is due to saffrons ability to support and nourish the nervous system and to improve cerebral circulation increasing circulation of blood in the brain and improving the health of the micro-capilliaries (2). It is important to seek professional advice for ongoing headaches to gain understanding of the root cause, as well as to ensure the correct course of treatment.

    Cardiovascular

    In another trial 50mg of saffron was dissolved in 100ml of milk and administered twice a day to 20 people of which 10 of them had heart disease. There was a consistent reduction in lipoprotein oxidation susceptibility observed after 3 and 6 weeks. This is good because lipid oxidation promotes premature coronary atherosclerosis and is also implicated in other cardiovascular disorders. This is potentially due to the antioxidant effect of saffron (16).

    Science has shown that saffron has hypotensive, anti-ischemic, anti-platelet aggregation, anti-atherosclerotic, antioxidant, anti-diabetic and hypolipidemic effects which is why this plant can be considered as a potential treatment for cardiovascular health or a valuable part of a more complex formulation (15).

    Alzheimers

    2 separate clinical trials were conducted on patients with mild to moderate Alzheimer’s disease. The efficacy of treatment was evaluated using the AD Assessment Scale and cognitive subscale, as well as the Clinical Dementia Rating Scale. The research shows that saffron produced a significantly superior outcome on cognitive function when compared to placebo. The effectiveness of improving cognition was equal to that of the pharmaceutical donepezil. Both decreased the score in Clinical Dementia Rating Scale by 0.7-0.8, and the Alzheimer’s Disease Assessment Scale by 3.7.

    Premenstrual syndrome

    A study showed that administration of 15mg twice a day saffron capsules, for 2 menstrual cycles helped reduce depression score on the Hamilton Depression Rating Scale. The saffron extract also reduced menstruation symptoms when compared to placebo.

    Serotonin, or 5-hydroxytryptamine, is a mood-elevating neurotransmitter synthesized from tryptophan (an amino acid). Serotonin plays a key role in such body functions as mood, sleep, digestion, nausea, wound healing, bone health, blood clotting and sexual desire.

    Hormones and gynaecology

    Saffron is indicated for a number of gynaecological conditions associated with blood deficiency. Specifically used to bring on a delayed menstruation or in dysmenorrhea (severe menstrual cramps and pain). Saffron improves tissue health in the female reproductive system, due to its ability to improve blood flow to the reproductive organs. Saffron is sometimes used in Ayurvedic medicine as part of an approach for treating fertility issues. Particularly those caused by depressed tissue states (dry and cold condition of the epithelium- mucous membranes of the reproductive system, which is sometimes rooted in nutritional deficiency or poor circulation, for both of which saffron can be supportive). It is important to seek professional advice for fertility issues to gain understanding of the root cause and as well as to ensure the correct course of treatment. Herbal medicine can be very supportive for fertility issues as shown by our case studies.

    A well known aphrodisiac, Saffron promotes tissue growth and circulation to the reproductive organs, improving virility, libido and sexual function in both men and women (1,2).

    A study showed that administration of 15mg twice a day saffron capsules, for 2 menstrual cycles helped reduce depression score on the Hamilton Depression Rating Scale. The saffron extract also reduced menstruation symptoms when compared to placebo (20).

    Serotonin, or 5-hydroxytryptamine, is a mood-elevating neurotransmitter synthesized from tryptophan (an amino acid). Serotonin plays a key role in such body functions as mood, sleep, digestion, nausea, wound healing, bone health, blood clotting and sexual desire.

    Immune system

    Saffron contains numerous antioxidant compounds, suggesting that it may be useful in an adjunctive approach to improve cellular health. There is some promising research into the application of saffron as a chemoprotective (5,6). A chemoprotective is a herb or medicine that can be used to protect healthy tissue from the side effects of certain anticancer drugs. Studies have shown saffron has potential antioxidant, antimutagenic, tumoricidal, antigenotoxic properties. There has been much research around saffron for many different kinds of cancer including skin, colorectal, liver and many more. However much of the research has been conducted on cells and animals. Therefore, more investigations need to be conducted to see if saffron can be useful with cancer as an adjunctive treatment. Plants can be not only potentially valuable for direct cancer treatment, but also for alleviating the side effects of conventional treatment (14).

    Saffron is a rich source of carotenoids making it a potent cell oxygenator. These carotenoids have been shown to increase the supply of oxygen in the blood cells (6). This can support optimal function of immune cells, as low oxygen levels have been shown to impede immune function. Generally better oxygenation benefits all cells in the body.

    It takes around 160 flowers to produce 1g of saffron.

Additional information

  • Botanical description

    An autumn-flowering perennial, saffron has been in cultivation and use for more than 3,500 years across many cultures, continents, and civilisations. Saffron has a corm (otherwise described as a bulbo-tuber- likened to both a bulb and a tuber), from which grows the leaves, bracts, bracteole, and a single flowering stalk. C. sativus generally blooms with a single beautiful deep purple flower in the autumn, from which 3 red / orange stigma grow, these are what makes up the well loved spice used in herbal medicine and eastern cuisine today. The whole plant grows up to around 10 to 30 cm high.

    As a result of selective breeding Crocus sativus species is sterile, meaning that it is unable to reproduce. Therefore this species does not grow in the wild. The plant’s genetic fault is thought to have been caused by a hybridisation with an earlier form of this plant, C. Cartwrightianus, which native to Greece, yet this is not fully understood.

  • Common names

Aromatic
An ‘aromatic’ remedy, high in volatile essential oils, was most often associated with calming and sometimes ‘warming’ the digestion. Most kitchen spices and herbs have this quality: they were used both as flavouring and to ease the digestion of sometimes challenging pre-industrial foods. Many aromatics are classed as ‘carminatives’ and are used to reduce colic, bloating and agitated digestion.They also often feature in respiratory remedies for colds, chest and other airway infections. They are also classic calming inhalants and massage oils, and are the basis of aromatherapy for their mental benefits.
Astringent
The astringent taste you get with many plants (the most familiar is black tea after being stewed too long, or some red wines) is produced by complex polyphenols such as tannins. Tannins are used in concentrated form (eg from oak bark) to make leather from animal skins. The process of ‘tanning’ involves the coagulation of relatively fluid proteins in living tissues into tight clotted fibres (similar to the process of boiling an egg). Tannins in effect turn exposed surfaces on the body into leather. In the case of the lining of mouth and upper digestive tract this is only temporary as new mucosa are replenished, but in the meantime can calm inflamed or irritated surfaces. In the case of open wounds tannins can be a life-saver – when strong (as in the bark of broadleaved trees) they can seal a damaged surface.One group of tannins, the reddish-brown ‘condensed tannins’ are procyanidins, which can reduce inflammation and oxidative damage.
Bitter
Bitters are a very complex group of phytochemicals that stimulate the bitter receptors in the mouth. They were some of the most valuable remedies in ancient medicine. They were experienced as stimulating appetite and switching on a wide range of key digestive functions, including increasing bile clearance from the liver (as bile is a key factor in bowel health this can be translated into improving bowel functions and the microbiome). Many of these reputations are being supported by new research on the role of bitter receptors in the mouth and elsewhere round the body.Bitters were also seen as ‘cooling’ reducing the intensity of some fevers and inflammatory diseases.
Cooling
Traditional ‘cold’ or cooling’ remedies often contain bitter phytonutrients such a iridoids (gentian), sesiquterpenes (chamomile), anthraquinones (rhubarb root), mucilages (marshmallow), some alkaloids and flavonoids. They tend to influence the digestive system, liver and kidneys. Cooling herbs do just that; they diffuse, drain and clear heat from areas of inflammation, redness and irritation. Sweet, bitter and astringent herbs tend to be cooling.
Hot
Traditional ‘hot’ or ‘heating’ remedies, often containing spice ingredients like capsaicin, the gingerols (ginger), piperine (black or long pepper), curcumin (turmeric) or the sulfurous isothiocyanates from mustard, horseradich or wasabi, generate warmth when taken. In modern times this might translate as thermogenic and circulatory stimulant effects. There is evidence of improved tissue blood flow with such remedies: this would lead to a reduction in build-up of metabolites and tissue damage.Heating remedies were used to counter the impact of cold, reducing any symptoms made worse in the cold..
Mucilaginous
Mucilages are complex carbohydrate based plant constituents with a slimy or ‘unctuous’ feel especially when chewed or macerated in water. Their effect is due simply to their physical coating exposed surfaces. From prehistory they were most often used as wound remedies for their soothing and healing effects on damaged tissues. Nowadays they are used more for these effects on the digestive lining, from the throat to the stomach, where they can relieve irritation and inflammation such as pharyngitis and gastritis. Some of the prominent mucilaginous remedies like slippery elm, aloe vera and the seaweeds can be used as physical buffers to reduce the harm and pain caused by reflux of excess stomach acid.Mucilages are also widely used to reduce dry coughing. Here the effect seems to be by reflex through embryonic nerve connections: reduced signals from the upper digestive wall appear to translate as reduced activity of airway muscles and increased activity of airway mucus cells.Some seed mucilages, such as in psyllium seed, flaxseed (linseed) or guar bean survive digestion to provide bulking laxative effects in the bowel. These can also reduce rate of absorption of sugar and cholesterol..
Pungent
The pungent flavour refers to the powerful taste of hot spices including mustard (Brassica spp.), ginger (Zingiber officinale), horseradish (Amoracia rusticana), chilli (Capsicum spp.), and garlic (Allium sativum). These herbs act to enliven and invigorate the senses, and they often also have heating qualities. Unlike other tastes, the effect is not linked to a specific receptor on the tongue and instead acts through direct irritation of tissues and nerve endings. Energetically, pungent herbs are known to disperse energy (qi) throughout the body. Pharmacologically, pungent herbs dry excess moisture and mucus, as well as stimulate digestion and metabolism.
Resinous
Resins are most familiar as tacky discharges from pine trees (and as the substance in amber, and rosin for violin bows). They were most valued however as the basis of ancient commodities like frankincense and myrrh (two of the three gifts of the Three Wise Men to the baby Jesus) and getting access to their source was one benefit to Solomon for marrying the Queen of Sheba (now Ethiopia). Resins were the original antiseptic remedies, ground and applied as powders or pastes to wounds or inflamed tissues, and were also used for mummification.With alcohol distillation it was found that they could be dissolved in 90% alcohol and in this form they remain a most powerful mouthwash and gargle, for infected sore throats and gum disease. They never attracted much early research interest because they permanently coat expensive glassware! For use in the mouth, gums and throat hey are best combined with concentrated licorice extracts to keep the resins in suspension and add extra soothing properties. It appears that they work both as local antiseptics and by stimulating white blood cell activity under the mucosal surface. They feel extremely effective!
Salty
The salty flavour is immediately distinctive. A grain dropped onto the tongue is instantly moistening and a sprinkle on food enkindles digestion. This easily recognisable flavour has its receptors right at the front of the tongue. The salty flavor creates moisture and heat, a sinking and heavy effect which is very grounding for the nervous system and encourages stability. People who are solid and reliable become known as ‘the salt of the earth'.
Sharpness
The sharp taste of some fruits, and almost all unripe fruits, as well as vinegar and fermented foods, is produced by weak acids (the taste is generated by H+ ions from acids stimulating the sour taste buds). Sour taste buds are hard-wired to generate immediate reflex responses elsewhere in the body. Anyone who likes the refreshing taste of lemon or other citrus in the morning will know that one reflex effect is increased saliva production.Other effects are subjective rather than confirmed by research but there is a consistent view that they include increased digestive activity and contraction of the gallbladder.
Sour
The sour taste occurs because of the stimulation of hydrogen ions which trigger the sour taste receptors on the tongue. The more acidic a substance, the more hydrogen ions will be released. The sour taste comes from acidic substances including citrus, fermented foods, tannins, and vinegars. Sour foods and herbs absorb excess moisture, whilst also increasing the production of saliva. Energetically, sour substances tonify the lungs, playing a role in disease prevention. Excessive use, however, can result in malabsorption of nutrients. Examples of sour herbs include, rosehips (Rosa canina), raspberry (Rubus idaeus), rhubarb (Rheum palmatum), schisandra (Schisandra chinensis), hawthorn (Crataegus monogyna) and ginkgo (Ginkgo biloba).
Sweet
In the days when most people never tasted sugar, ‘sweetness’ was associated with the taste of basic foods: that of cooked vegetables, cereals and meat. In other words sweet was the quality of nourishment, and ‘tonic’ remedies. Describing a remedy as sweet generally led to that remedy being used in convalescence or recovery from illness.Interestingly, the plant constituents most often found in classic tonics like licorice, ginseng are plant steroids including saponins, which also have a sweet taste.
Umami
The umami taste was originally discovered in 1985 in Japan and is directly translated from the Japanese as a ‘pleasant savoury taste’. It is referred to as the ‘fifth taste’ and is a salty, rich, and meaty flavour. The umami flavour is produced by amino acids (glutamic acid and aspartic acid) found in many food and plant sources including tomatoes, mushrooms, seaweeds and soy-based foods. Umami foods can improve nutritional absorption and digestion as there are also umami receptors in the gut as well as the mouth. Examples of umami herbs include green tea (Camellia sinensis), reishi (Ganoderma lucidum), nettle (Urtica dioica), cordyceps (Ophiocordyceps sinensis), shitake (Lentinula edodes) and bladderwrack (Fucus vesiculosus).
