Amphoteric

Amphoterics are herbs that balance and normalise the function of an organ. Amphoteric herbs are able to act bidirectionally — for example, they may increase or decrease blood pressure, dependent on the change needed to restore homeostasis. They often act on the endocrine system, including on the hypothalamic-pituitary axis to restore hormonal function. Examples of amphoteric herbs include liquorice (Glycyrrhiza glabra), hawthorn (Crataegus monogyna), agnus castus (Vitex agnus-castus) and black cohosh (Actea racemosa).
