People of the Amazon have a history of using Suma as an aphrodisiac and a tonic.

' Suma works as an adaptogenic tonic, gently increasing vitality and stamina and overall well-being.  It tones, balances and strengthens the body, stimulating the immune system and muscle growth.  It also calms the nerves and has an uplifting effect.  This is particularly beneficial if stress is diminishing sexual desire.
