The story
What makes it unique
Trichosanthes kirilowii contains trichosanthin, a ribosome-inactivating protein. The fresh young fruit is high in water and fiber, digested slowly, and provides low energy density. However, raw consumption is hazardous due to toxic proteins that require denaturation through cooking or specific traditional processing.
