Suma (Hebanthe eriantha) is known as Brazilian Ginseng for its reputation as an adaptogen.
Pfaffia paniculata is a synonym of Hebanthe eriantha. Gomphrena paniculata is a synonym of Hebanthe eriantha too, but Gomphrena is the name of a completely different genus of plant than Hebanthe.
Hebanthe eriantha is referred to as "para todo", which means in Spanish, for everything.
Suma raises estrogen, progesterone and testosterone. The effect of increased estrogen and progesterone are useful for herbal breast enhancement. Estrogens are formed from androgens. However, for breast growth, there must be a higher ratio of bodily estrogens than androgens.
Suma is known for increasing fertility, and this is likely because of its estrogen, progestogen and androgen raising properties.
The part of Suma used is its root.
