Great, low-maintenance plant, that prefers shade. High protein content, apparently a complete protein. Leaves, flowers, and little fruit it makes are edible. Has a pleasant, nutty taste. But, eaten in large quantities can be toxic.
Multiple strong medicinal benefits. Saw this general guideline in an article:
"To reduce the side effects of katuk leaf, should consume in small amounts (maximum of 50 g per day), leaf cooked first, and do not consume continuously for more than 3 months."
So best used as a supplemental plant, not the main course.
