Vallarai should however, not be confused with Brahmi, as the former is grown naturally on the banks of ponds, streams, rice fields and even at home without much effort. The leaves of the plant, which is slightly bitter in taste, could be dried and powdered, and a quarter teaspoon of the powder could be taken regularly as a general tonic by adults or could be included while cooking food.
Vallarai tonic is also found to improve memory power among children, when given in small proportions by mixing concentrated aqueous extracts with sugar and honey. The tonic does not require any terminal processing, except addition of milk, to a tablespoon of the tonic.
Vallarai, being a well-known traditional herb in India, is mainly used as an alternative tonic and diuretic, and with no side effects being found, it is safe for use. Pregnant women should however, consult a physician prior to use.
