Angostura Overview

Angostura Angostura is a shrub-like tree native to Venezuela and other tropical areas of South America, growing up to 4-5 meters high with smooth, gray bark. The bark is used in medicine, particularly for its properties in treating fever, diarrhea, preventing recurrence of malaria, and as an antispasmodic. When taken in large doses, angostura can have cathartic and emetic effects. In foods, angostura is used in alcoholic beverages, although angostura bitters no longer contain angostura, but gentian and other bitters. The bark contains angostura bitters 1 and 2, alkaloids like cuspareine, cusparine, and galipine, as well as a volatile oil. Galipinine and other alkaloids in angostura have shown antimalarial effects in vitro, supporting its traditional use for malaria prevention. The alkaloids cusparine and galipine also exhibit antispasmodic effects in vitro. Angostura is considered Generally Recognized As Safe (GRAS) for use in foods in the United States.

Carbidopa, Levodopa Overview

  • The combination of levodopa and carbidopa is used to treat the symptoms of Parkinson's disease and Parkinson's-like symptoms that may develop after encephalitis (swelling of the brain) or injury to the nervous system caused by carbon monoxide poisoning or manganese poisoning. Parkinson's symptoms, including tremors (shaking), stiffness, and slowness of movement, are caused by a lack of dopamine, a natural substance usually found in the brain. Levodopa is in a class of medications called central nervous system agents. It works by being converted to dopamine in the brain. Carbidopa is in a class of medications called decarboxylase inhibitors. It works by preventing levodopa from being broken down before it reaches the brain. This allows for a lower dose of levodopa, which causes less nausea and vomiting.
