Causticum, or potassium hydrate, is a remedy used in homeopathy for a broad spectrum of conditions. It is available in several forms, including tablets, liquid, and cream.
Homeopathy is a medical system developed in Germany more than 200 years ago. It’s based on the belief that minimal doses of natural substances can help stimulate the body to cure itself.
