Papaya Leaf Extract

Carica papaya leaf has been used across West Africa, the Caribbean, and Southeast Asia in traditional wellness practices for centuries. Our papaya is sourced fresh, cold-extracted, and fermented for 5 days to maximize bioavailability of its active botanical compounds.

The Fermentation Science

Sorghum Bicolor

Known as guinea corn across West Africa, Sorghum bicolor is rich in polyphenols and 3-deoxyanthocyanidins studied for their botanical properties. Co-fermented with papaya — the preparation period shown in peer-reviewed research to produce the highest measured antisickling properties among all preparations tested.

Sorghum Research

"The highest antisickling properties among all preparations tested."
