• Leaves: Used in decoctions for diabetes, worms, and skin conditions.

• Seeds: The seeds from the ripe red fruit are also used in traditional preparations for their anthelmintic and antidiabetic properties.

4. Phytochemicals specific to the plant and their action.

The bitter taste and medicinal power of Momordica charantia come from a suite of unique compounds.

Charantin: A steroidal glycoside that is a principal Hypoglycemic agent. It is more potent than the drug tolbutamide and works by increasing glucose uptake and glycogen synthesis in the liver, muscle, and adipose tissue.

Polypeptide-p (Plant Insulin): An insulin-like polypeptide that has been shown to lower blood glucose levels when injected subcutaneously in human and animal studies. It is sometimes referred to as "p-insulin."

Momordicine: Alkaloids responsible for the bitter taste. They stimulate digestive juice secretion and have Anthelmintic and Antiviral properties.

Vicine: A nucleoside that may contribute to the hypoglycemic effect.

Lectins: Proteins that bind to carbohydrates and may have an insulin-like activity, reducing blood glucose concentrations.

Antioxidants (Vitamin C, Flavonoids, Phenols): Help combat oxidative stress associated with diabetes and protect against cellular damage.
