Scientific Studies on Bitter Melon

Many laboratory studies have been done to identify the chemical substances in the plant. Their analyses identified more than 200 substances which created chemical reactions with possible medicinal effects. These tests gave scientific evidence and bases for the plant’s health benefits,

  • reduce sugar levels in the blood
  • treatment for intestinal worms
  • protection against viral and bacterial infections
  • help in weight loss and obesity
  • fever and pain relief
  • liver protection
  • treatment of skin infections

Several studies on lab animals including diabetic mice conducted. Treatment with extracts of bitter melon resulted in significant reductions in fat and cholesterol in the blood.  A promising study indicated the potential for preventing or alleviating the effects of stroke and nerve damage.

Much more significant findings were obtained from a number of clinical trials on human patients with diabetes. The plant was shown to be able to greatly reduce the amount of blood sugar, sometimes in short lengths of time. The results here are more conclusive and more applicable to show the potential use of bitter melon as a cure for diabetes and obesity.

The Health Benefits of Phytochemicals in Bitter Melon

Several groups of chemical substances identified in the plant called phytochemicals. They have properties which can help cure a number of deadly illnesses. Some of these substances were first discovered and exist in bitter melon. Lab tests conducted to study these groups. Their results revealed the health benefits they bring to us.

Group of protein-based substances inhibits the replication of viruses and cancerous cells. Because of this property, this group has been classified as “ribosomal inactivating proteins” or RIPs. Ribosomes are the part of the cell where DNA can be found. This implies that RIPs could stop replication at the DNA level. Among the notable RIPs are momordin II, momorcharins, and MAP30. These have been able to stop the spread of cancer cells from the liver. And even the virus causing AIDS.

Another group of phytochemicals has a structure made up of chains of sugar molecules called polysaccharides. These substances are partly the cause for bitter melon’s anti-diabetic benefit. These also function as antioxidants to protect cells in the nerves and the immune system. Some phytochemicals are similar in structure and function to the insulin and act the same way to lower blood glucose. This gives the bitter melon the title: “vegetarian insulin”

A number of substances found in bitter melon belong to a group called saponins. The name “saponins” comes from their soap-like physical structure. These are mostly responsible for bitter melon’s ability to regulate sugars and fat in the blood. Preventing diabetics and obesity.
