Indian Snakeroot Overview
Indian snakeroot (Rauvolfia serpentina), also known as sarpagandha, is a plant that is native to India and other parts of South Asia. It is a perennial shrub and has been traditionally used in Ayurvedic and Unani medicine as a treatment for a variety of conditions, including hypertension (high blood pressure), anxiety, and insomnia.

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.
