Extracts from bitter melon are also used against stress-induced ulcer in rats, pylorus ligation, and aspirin (3).

Moreover, bitter melon also has antihelminthic agents, which help get rid of intestinal parasites in the body. These agents kill parasitic worms without causing any significant damage to people or animals carrying the parasite (4).

2. Has anticancer properties

Although more research is still required, complementary treatments using bitter melon in cancer patients have shown encouraging results. 

The following conditions have also been demonstrated when bitter melon extracts are used:

  • Enhanced detoxification
  • Prevention of lipid peroxidation
  • Inhibit damage caused by free radicals

According to another research study, bitter melon contains more than 20 active components that possess anticarcinogenic properties (5).

Bitter melon is also known to be helpful in reducing the symptoms of certain conditions that affect the respiratory tract. These conditions include hay fever, asthma, and bronchitis.

Bitter melon contains anti-inflammatory, antihistamine, and antiviral properties making it an ideal supplementary food that can help maintain a healthy respiratory system. 

4. Improves eyesight and vision

Bitter melon contains alpha-Carotene, beta-Carotene, zeaxanthin, and lutein, which are flavonoids that improve eye health. These flavonoids not just help improve night vision and eyesight but also slow down macular degeneration. 

These compounds present in bitter melon play a significant role when it comes to eliminating reactive oxygen species that can cause a number of complications, getting rid of oxygen-derived free radicals, as well as fighting the effects of old age. 

5. Boosts immunity

When bitter melon is added to the diet as a vegetable, juice, or fruit, the immune system tends to become stronger in fighting diseases as well as promote a faster recovery from common illnesses. This is perhaps due to bitter melon's antioxidant properties, which provide a strong line of defense against germs. 

Bitter melon has a high vitamin C level, making it a powerful antioxidant. 

6. Helps regulate blood sugar levels 

In alternative medicine, Momordica charantia is used for diabetes management and lowering blood glucose levels. As a matter of fact, it is common for some Asian countries to have decoctions of bitter melon to help regulate blood sugar levels. 

Bitter melon contains structural components that are similar to animal insulin. Its phytochemical composition includes alkaloids, steroidal saponins, and charantin. 

Charantin particularly enhances glycogen synthesis in the muscles and liver. Altogether, these compounds significantly contribute to bitter melon's ability to reduce blood sugar levels in people with type 2 diabetes. When bitter melon becomes part of a regular diet, it can provide hypoglycemic effects along with taking medications for diabetes. 

7. Helps manage skin-related conditions

For centuries, bitter melon has been widely used in both traditional Chinese medicine and Ayurveda for the treatment of a number of skin problems. 

Because of bitter melon's antimicrobial properties, it can help fight against various skin conditions, such as scabies, ringworm, and psoriasis. This fruit tends to stop the activity of guanylate cyclase, which induces the worsening symptoms of psoriasis.

8. Aids in digestion and promotes weight loss

Every 100 grams of bitter melon only contains 17 calories. Even though it is low in calories, it is high in vitamins, minerals, and dietary fiber. Consuming bitter melon also helps prevent constipation as well as relieve indigestion due to its high dietary fiber. 

Bitter melon may also help in weight loss since it contains high levels of charantin that can help enhance glycogen synthesis and glucose uptake, resulting in a decreased fat cell storage. 

9. Promotes healthy bones

Vitamin K is an essential nutrient found in bitter melon. This vitamin plays a significant role when it comes to the regulation of blood clot formation. Moreover, Vitamin K helps distribute calcium all over the body, which then helps increase bone density and lowers your risk of having a bone fracture.

For this reason, people with bone problems such as osteoporosis should think about consuming vitamin K-rich foods like bitter melon. A lack of vitamin K may cause prolonged and heavy menstrual bleeding, blood clotting abnormalities, easy bruising, and bone fractures. 


In spite of bitter melon's unpleasant appearance and off-putting taste, it sure provides a number of health benefits. Among these health benefits, the most well-known is its ability to regulate blood sugar levels in people who have diabetes.
