Policosanol? Policosinol is a common misspelling of policosanol.
Policosanol is an herbal supplement that is claimed to help lower cholesterol. It is a "natural" product that consists of fatty alcohol derived from plant waxes. Even though policosanol is a natural product, it does not mean that it is suitable for everyone. Potential side effects include insomnia, migraines, and an upset stomach.
