Lachesis is a classical homeopathic remedy prepared from the venom of the bushmaster snake (Lachesis muta), an animal source. In homeopathic practice it is traditionally associated with left-sided complaints, an aversion to anything tight around the neck or waist, and the flushes and intensity often described around menopause.
This page explains where Lachesis comes from, its classic indications, the characteristic picture homeopaths recognise, and the forms and potencies it is commonly made in.
The short version: Lachesis is the intense, talkative, left-sided remedy that cannot bear tight clothing and feels worse after sleep.
Where does Lachesis come from?
Lachesis is prepared from the venom of the bushmaster, a large pit viper of Central and South America. A minute quantity of venom is diluted and succussed many times over in the homeopathic way, so the finished remedy carries only the homeopathic imprint of the venom and none of its material toxicity. It is used on the principle of like-with-like.
What is Lachesis traditionally used for?
Lachesis is a much-described remedy in homeopathic literature. It is traditionally associated with:
- Left-sided complaints, or symptoms that begin on the left and move right.
- An intolerance of tight clothing, especially around the neck and waist.
- Flushes of heat and congestion, often described around menopause.
- Feeling worse after sleep, waking with aggravated symptoms.
- A talkative, intense state of mind, sometimes with jealousy or suspicion.
Who typically reaches for it?
The Lachesis picture is vivid and intense. The person is often lively and talkative, dislikes anything constricting at the throat or waist, and feels notably worse on waking from sleep. Symptoms tend to favour the left side, and there may be flushes, congestion and a sense of pressure that eases once a discharge or flow begins. This blend of left-sidedness, sensitivity to constriction and post-sleep aggravation is what guides a homeopath toward Lachesis.
What forms and potencies does it come in?
Lachesis is prepared as a homeopathic dilution and is commonly found as small dissolving pillules or tablets, as well as in liquid drops and combination formulas. In home self-care it is most often used in low potencies such as 6C or 30C, while higher potencies are generally chosen with the guidance of an experienced practitioner.
As with any homeopathic remedy, potency and repetition are matched to the individual picture rather than to a diagnosis, so it helps to read the label and, where useful, check in with a qualified homeopath.
