Ignatia
Ignatia is a homeopathic remedy derived from the bean of a small tree native to the Philippine Islands and China. The beans contain a substantial amount of strychnine, a bitter substance often used in rat poison. Strychnine is fatal to humans if taken in large doses. Small doses cause headaches, loss of appetite, cramps, muscle twitching, trembling, frightening dreams, cold sweat, nervous laughter, and giddiness. Ignatia is one of the best remedies for conditions brought about by emotional upset, such as grief, shock, jealousy, fear, anger, depression, embarrassment, fright, or ridicule.
