Is Cantharides Tincture Vegan?

Cantharides tincture is a liquid preparation made from the Spanish fly (Lytta vesicatoria), an insect known for its blistering properties. Historically, it has been used in traditional medicine for its ability to cause irritation and blistering, which was believed to stimulate healing in certain conditions. However, its use has largely fallen out of favor due to its toxic nature and the availability of safer alternatives.
