This is general information about a homeopathic remedy, not a prescription or dosing advice. In homeopathy the correct remedy and potency are chosen for the whole individual symptom picture by a qualified homeopath — the same remedy is not right for everyone. Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.

The characteristic picture & modalities

Agnus Castus, from the chaste tree, is chiefly associated with marked loss of sexual desire and vigour, especially in men, alongside despondency and a sense of being prematurely old. The picture often includes low confidence, absent-mindedness and the effects of past over-indulgence, with coldness and relaxation of the body. There are also some hormonal and low-milk lactation uses. This is a recognisable state of sexual debility shadowed by low spirits, describing a constitutional tendency that fits certain people rather than serving as a diagnosis.

Before you take Agnus Castus

A qualified homeopath matches remedy, form and potency, whether tincture or higher dilution, to your whole picture and not to low libido in isolation. This page is informational background, not a prescription, and you should not self-select a potency. Sexual difficulties, hormonal complaints and persistent low mood deserve proper medical and, where relevant, psychological assessment to identify underlying causes. For anything severe, ongoing or distressing, seek that medical opinion first, and let homeopathy be an individualised conversation with a practitioner alongside it.
