What can I use it for?
California poppy can ease nervous tension. It is beneficial to helps bring about sleep if taken before bedtime. When one is feeling tired and wired, it can help calm and bring about a state of relaxation. Â
As a herb that is gifted with antispasmodic nervine actions, California poppy may also  be used to ease spasm in the digestive system and in the urinary tract. This may be applied in conditions such as irritable bowel syndrome and enuresis.Â
It is also useful to relax the tension of muscular aches. This may be best achieved by a combined approach using a tea made from the fresh flowers and perhaps an accompanying salve to be taken after a hard dayâs physical labour. Those with spasmodic conditions associated with the nervous system such as neuralgia and neuropathy will also likely find benefit from using this herb regularly.
California poppy has a relaxing effect on the nervous system which also makes it useful to use during acute bouts of anxiety or to assist during panic attacks. With its gentle nervine relaxant effect, it may also be used for insomnia, restlessness and migraines.
It is non-addictive and safe for all ages, in fact it is especially indicated for children for its gently sedative effects and additionally for colic.

Into the heart of california poppy
California poppy has a long tradition of use in Western herbal medicine for calming the nervous system and has been used for states of unrest such as insomnia, nervous agitation and mild to moderate pain. It can be used for any such presentations in children too including over-excitability.
California poppy is an excellent nervine that is energetically both cooling and relaxing. This combination of properties offers a perfect antidote to a hot and wired system. This herb may be indicted where there is a hyperactive or agitated state in the nervous system. The positive potential of this plant is to enable calmness and centring one through times of acute stress.
This herb is often used to support in anxiety. It is popular for use in plant medicine for grounding the nervous system where repetitive thoughts or worries plague the mind.Â
California poppy may be used for pain that interferes with sleep or for pain in the nerves such as is experienced in sciatica and shingles. This can be applied both topically and internally.
California poppy is thought to have an affinity to the emotional heart. This is due to its dynamic combination of hypotensive, antispasmodic and nervine actions. It is indicated where stresses and strains link to the nervous system causing symptoms in the heart and vascular system. These may be symptoms such as increased heart rate, mild chest pain and palpitations.Â
It can be used to gently relax these tensions, harmonising the mind to bring a sense of calm and serenity to the heart.

Traditional uses
California poppy has a long tradition of use in Western herbal medicine for calming the nervous system, being used for states of unrest such as insomnia, nervous agitation and mild to moderate pain. It can be used for any such presentations in children too, including over-excitability.
It was used by Native Americans as a food, (the whole plant was cooked and eaten as a vegetable) and as a medicine in various preparations for both children and adults. Tribes from different parts of California used the plant in various ways and for a variety of conditions. The Mendocino used a root preparation applied to a painful tooth, taken for stomach aches or applied as a wash for headaches.
The Costanoan tribes used a decoction of the flowers to promote healthy sleep and as a preparation to be rubbed into hair to kill lice. The Chumash made a poultice of the seed pods to halt lactation in breast-feeding.

Traditional actions
Herbs can have a wide variety of actions within the body. See the list below for this herbâs specific herbal actions.
-
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
Nervous system
California poppy is primarily used these days for its effects on this system. It is dose-dependent, so at lower doses it has anxiolytic effects and at larger doses becomes more sedating and analgesic.
Childrenâs remedy
It is often prescribed in children as a sleep aid when there is anxiety, pain, over-excitability. Some of the literature suggests it can be helpful for bedwetting.
Pain
It is a favoured remedy of many herbalists for the use in minor aches and pains, especially if this is associated with nervous tension. It has a tradition of use headaches and for colicky pains, so can help to ease cramps, spasms and is well-indicated for irritable bowel syndrome. For overworked muscles it can be taken in the form of a strong tea, perhaps whilst relaxing in an Epsom salts bath; both remedies helping to ease the soreness.
Insomnia
It is used to a good effect for quietening an overactive mind that keeps one wakeful with inner monologue and also to help with the initiation and maintenance of sleep if disturbed by mild pain.
In combination
It is often mixed in with other nervous system relaxants where there can be a synergistic effect. It combines well with passionflower for hyperactivity and sleep disturbances but other combinations work well too, such as a blend with hops and valerian.
There are combinations that have been studied which are covered in the Evidence section, including in with another member of the poppy family Corydalis cava, where the analgesic effects were looked at and studies in combination with valerian (in insomnia) and hawthorn (in anxiety).
-
Research
Extracts have been shown to inhibit adrenalin synthesis and enzymatic breakdown of catecholamines in vitro, contributing to the herbâs calming properties.
In an in vitro study, a 70% ethanol extract of California poppy was able to bind to serotonin receptors 5-HT(1A) â these are responsible for neuromodulation, decreasing blood pressure & heart rate by blood vessel dilation and stimulation of the vagus nerve. The activity on the 5-HT(1A) receptor was at least partly due to the presence of the aporphine alkaloidN-methyllaurotetatanine. An extract combination of Californian poppy and Corydalis bound to opioid receptors in vitro which shows promise to explain in part the tradition of use as a pain reliever.
In a double-blind randomised controlled trial a combination of California poppy, Hawthorn (Crataegus oxycantha) and Magnesium was compared to placebo to evaluate safety and efficacy of the combination on mild to moderate anxiety disorders. The Hamilton anxiety scale, somatic scores and change in patient self-assessment showed that anxiety fell during treatment. The combination proved safe and more effective than placebo.
A more recent prospective 4 week observational study on a combination of Californian poppy and Valerian (Valeriana officinalis) was carried out on adults with insomnia within a GP practice. Sleep efficiency increased with the duration and frequency of night awakenings decreasing and there was a decrease in anxiety.
Of course, the above combinations donât distinguish between the herbs within and more studies are needed on Eschscholzia alone. From other research the findings are that the relatively low levels of alkaloids in the aerial parts of the plant mean higher doses are needed for a sedative effect than an anxiolytic effect.

Did you know?
The opium poppy â Papaver somniferum is renowned for possessing excellent sedative properties. The opioids, (alkaloids within the plant) are utilised by the medical profession in the production of codeine and morphine. As well as the strong sedative quality, morphine is an extremely powerful analgesic which herbalist doctors in Germany are allowed to prescribe. California poppy is a far safer distant cousin. As it contains no morphine it is a non-addictive, safe option and is actually used within programmes of opiate withdrawal.

Safety
Few comprehensive clinical studies have been carried out to explore its role in the management of pain, however California poppy has a long history of use and despite it being a member of the Papaveraceae (poppy) family, it is considered one of the safest anodynes in our herbal dispensary and is often prescribed for children.
No health risks following proper administration have been recorded, including during pregnancy and lactation, however it is wise to use safer alternatives or seek the advice of a qualified herbalist before use in these circumstances.
California poppy may bind with the same receptors as those targeted by certain antidepressants (SSRIs or MAO inhibitors), so it should be avoided here.
One also needs to be mindful that it is likely to have an additive effect when taken with other sedatives or analgesics, whether pharmacological or herbal.
Finally, it is wise to be very cautious when treating children with analgesic doses of this herb, (which tend to be higher than those to reduce anxiety). Use for the shortest possible time on the lowest effective dose for pain, again, seeking the advice of a qualified practitioner beforehand.
-
Preparation
California poppy can be taken as a tea made from dried or fresh herb, or alternatively may be extracted and preserved in alcohol, to then be taken in its tinctured form. Preparations made from the fresh plant material are considered more potent, whether used as a tea or tincture.
-
Dosage
For a tea, use 2â6 g of dried herb per dose as an infusion.  Two to three cups daily or a single cup at night.
Due to California poppy’s bitter taste, this herb may be enjoyed more as a tea as part of a blend, or a tincture may be more palatable.
As a tincture, 3â6 ml of a 1:2 strength tincture is recommended daily. Drop doses can be given.
-
Plant parts used
The whole of the aerial parts of the plant are used in herbal medicine, sometimes in combination with the roots.
-

Habitat
This graceful hardy annual, or perennial in warmer climates, is native to western North America and is the state flower of California. It has adapted to grow well in Mediterranean countries and grows well in the UK too, often cultivated for ornamental gardens. It is often found on grasslands and arid land, but is also found in coastal dunes, chaparral and coastal scrub, dry plains and coastal prairies, and the open slopes of pine or redwood forests.

Sustainability
This plant is classed as âapparently secureâ by Plant Serve following an assessment of its distribution in its native areas of the US. However, they state that the bigger threat to this plant is the genetic contamination of wild populations. This, coupled with the encroachment of human activities on the historic native habitat of this species is resulting in a large scale, human induced transformation in the distribution and genetic composition of this species.
Plant Serve also mention that focusing on identifying and delineating good quality, native populations of this plant in its native habitats are some of the efforts needed to conserve the genetic strength of this species. They also state the âa conservation strategy should be developed to maintain some such high-quality occurrences in which the gene pool appears to be relatively undiluted by introduced stock, and in which the species is occupying its historic habitatâ (11).
Habitat loss and over harvesting from the wild are two of the biggest threats faced by medicinal plant species. There are an increasing number of well-known herbal medicines at risk of extinction. We must therefore ensure that we source our medicines with sustainability in mind.Â
The herb supplement industry is growing at a rapid rate and until recent years a vast majority of medicinal plant produce in global trade was of unknown origin. There are some very real and urgent issues surrounding sustainability in the herb industry. These include environmental factors that affect the medicinal viability of herbs, the safety of the habitats that they are taken from, as well as the welfare of workers in the trade.
The botanical supply chain efforts for improved visibility (transparency and traceability) into verifiably sustainable production sites around the world is now certificated through the emergence of credible international voluntary sustainability standards (VSS). Read our article on sustainable sourcing of herbs to learn more about what to look for and questions to ask suppliers about sustainability.
-
Quality control
It is said that California poppy is best used fresh as opposed to dried herb form. It may also be tinctured from fresh herb.Â
Herbal Medicines are often extremely safe to take, however it is important to buy herbal medicines from a reputed supplier. Sometimes herbs bought from unreputable sources are contaminated, adulterated or substituted with incorrect plant matter.
Some important markers for quality to look for would be to look for certified organic labelling, ensuring that the correct scientific/botanical name is used and that suppliers can provide information about the source of ingredients used in the product.
A supplier should be able to tell you where the herbs have come from. There is more space for contamination and adulteration when the supply chain is unknown.

How to grow
California poppy is easy to grow. They prefer poor, well-drained soil in full sun. They do best in poor, well-drained soil and can be grown in exposed or coastal gardens, or in a mixed flower meadow.
- Sow in a drill springing seeds in thinly along the row. Use a trowel or your fingers to cover seeds very lightly with soil and water with a fine rose watering can.
- Sow seeds direct in situ where they are to flower between spring and autumn. These plants suffer if moved.Â
- Thin seedlings out once theyâre about 4cm tall and again at 8cm, so that theyâre spaced about 15cm apart.
- Deadhead regularly to ensure a long flowering period.

Recipe
California poppy tincture (using the whole fresh plant)
If you are lucky enough to live where these grow wild, leave them be and use only those youâve sown & grown. Try to harvest when there are a combination of flowers and seed heads on the plant.
Method:
- Gently shake the aerial parts free of bugs and dust, and if you are including the roots rinse those well.
- Cut into smallish chunks and put into a clean, wide-necked jar gently packing down and cover with vodka.
- Leave for a month or so upturning once or twice daily.
- Strain through a double layer of muslin and squeeze the plant material well to get as much liquid out as you can.
- Try drop doses of between 40- 80 (2-4ml) either straight onto the tongue or diluted in a little water. Maximum daily dose: 6ml.
