Bitter Melon Ext (fruit) Momordica Charantia

Bitter melon is also known as karalla fruit, bitter gourd, and balsam pear. It is a large trailing plant with wide leaves and tendrils. It produces melons that can be used as a food or medicinal supplement. It grows in the tropical areas of South America and Asia.

Bitter melon has been used for centuries as a popular food and medicine in South America, Asia, and India. It was traditionally used as a treatment for diabetes. Interestingly, bitter melon's use in diabetics continues to be its primary medicinal use today.

The main constituent of bitter melon is a steroidal saponin-charantin, and is the constituent responsible for the fruit's anti-diabetic effects. Other important constituents are polypeptide-p, triterpene glycosides, and alkaloids.

Again, bitter melon's main action is as an anti-diabetic. More recently, it has shown promise as anti tumor agent and may possess the ability to inhibit anti-HIV activity.

Bitter Melon Uses

Parts Used 

All aerial parts of the plant can be used. The entire fruit, including seeds, leaves, and stem, is considered medicinally active .

Bitter Melon Uses

Bitter melon' most prominent application is with the treatment of diabetes. It can be used in both Type I and Type II diabetes mellitus. Although the action of bitter melon is not strong enough to be a first line treatment in these individuals, it is a useful adjunctive treatment to any protocol.

Bitter melon has insulinomimetic properties, meaning it works similar to insulin. This may allow individuals with Type I diabetes to lower their insulin dose. Bitter melon is also thought to exhibit a sulfonylurea-like activity. Sulfonylurea medications are a conventional treatment for Type II diabetes and include medications such as Glyburide. [1]

Bitter melon improves glucose tolerance by enhancing tissue uptakes of glucose and by inhibiting glucose uptake from the intestines. These actions are all therapeutically beneficial for individuals suffering from diabetes mellitus. [2]

Preliminary studies in vitro have shown that certain proteins in bitter melon may inhibit growth of HIV. Of greatest interest is the protein MAP30. In various clinical applications, this protein has been shown to be reactive in different stages of the HIV life cycle, and has also exhibited efficacy for acute and chronic infections resulting from immunosuppression. [3]

Although, the direct mechanism of action is unknown, these same proteins have also been show to possess certain anti-tumor activities. [4] Further study is needed both in vitro and in human subjects, to further assess MAP30's effectiveness on certain cancers.

Bitter melon has also been proven effective as an adjunctive treatment for individuals on chemotherapeutic drugs. It has been shown in some studies to reduce the resistance to the “chemo” by cells. [5] The action is exerted on a particular cell's phenotype, thereby limiting the accumulation of chemotherapeutic drugs within the cell. The leaves are the primary plant components responsible for this effect.

Bitter Melon Toxicities

Side effects include hypoglycemia (low blood sugar), headache, increases in liver enzymes (hepatitis), and convulsions in children. [10] One of the constituents that occurs in the seeds, lectin, is toxic and can interfere with protein synthesis in the intestinal wall. [11]
