Suma

Pfaffia paniculata
Suma is often referred to as Brazilian ginseng, though it has no relationship to that herb, as its scientific name shows. It does, however, have some similar qualities. Both plants are adaptogenic, meaning that they bring the body into balance, aid the immune system and bolster energy. Naturally this has some bearing on the subject of aphrodisiacs, since health and sex drive are quite logically related. Flagging sexual appetites may therefore be restored by use of suma.
The scientific name also points out suma's role as panacea, since the root is useful in a variety of ways. Aside from the functions listed above, suma helps stabilize blood sugar, increases one's stamina and may even help reduce cancerous tumors.
Like most herbs, a certain minimum amount is required to make any difference. The minimum recommended daily dose for suma is 9 grams.
Suma. It does a body good.
