AKA: Ocimum basilicum.
There are over a hundred different varieties of basil.

Effects: Contains high amounts of cineole, a compound which increases blood flow to parts of the
brain. Said to increase concentration, mental functioning, and memory, relieve nervousness and
fatigue, and promote feelings of contentment, happiness, and sexuality. It has been used to treat
various respiratory infections, including bronchitis and whooping cough.

Precautions: Contains estragol, which may cause adverse reactions in some people and — possibly —
cancer in large doses (varieties low in estragol include Ocimum Americanum, Ocimum canum, and
Ocimum gratissimum). Constant use of basil may dull the mind, rather than stimulate it.
