Mahogany Seed Benefits and Side Effects

Sky fruit is the fruit of mahogany tree (Swietenia macrophylla) that grows in the majority of Asian countries. This fruit is also named “buah tunjuk langit” in the Malay language and 向天果/Xiang Tian Guo in chinese. It gets its unique name due to the way it hangs on the tree. Unlike most fruits, which hang downward, sky fruit hangs upward and its stalk points to the sky. In almost all countries where mahogany grows, sky fruit is commonly used as herbal remedy that helps improve blood circulation, treat diabetes, and cure impotence. Although scientific evidence affirming its efficacy as an herbal remedy is still weak, many people have already used it and anecdotal reports have recorded the health benefits of the fruit. Besides, the revelation of various substances that the fruit contains may give reliable scientific clues of how efficacious the fruit is and how numerous sky fruit health benefits are.

Sky Fruit Health Benefits

Sky fruit benefits can be revealed by looking into the health effects of chemical substances that the fruit contains. There are at least three active ingredients of sky fruit that are known to be beneficial for the health: flavonoid, saponin and alkaloids. We will look into the health benefits of the three active ingredients below.

  1. Flavonoid

Flavonoid is a phenolic compound that contains many pigments of the plant. Flavonoid is beneficial for human especially because it is an antioxidant that exterminates free radicals and toxins and improves immune system. The anti-oxidizing properties of the flavonoid content of sky fruit make the fruit effective for fighting various diseases caused directly or indirectly by oxidation, such as LDL buildup, high blood pressure and heart problem. The health benefits of the flavonoid content of sky fruit are briefly explained as follows.

  • Flavonoid improves cardiovascular system by smoothing blood circulation, clearing blood vessels from clogging cholesterol, and preventing arteriosclerosis plague.

  • Flavonoid has anti-inflammatory properties that prevent tissue inflammation.

  • Flavonoid acts as painkiller that numbs pain caused by tissue injury.

  1. Saponin

Saponin is a glucoside that forms soapy foam when mixed with water. It is a natural soap that is derived from plants and known to have hypoglycemic properties when consumed orally. The saponin content of sky fruit thus makes this fruit a potent natural remedy for people with diabetes mellitus. Although saponin is soap, it will not cause poisonous effect to warm-blooded animals when ingested. Based on a study conducted by Smith et al from Ekiti State University, Nigeria, and published in the Journal of Drug Delivery & Therapeutics, the hypoglycemic effect of saponin is even stronger than that of generic antidiabetic drugs, especially metformin. It is thus plausible for us to conclude that using mahogany seeds for diabetes treatment is one of the best natural ways to maintain normal level of sugar in the blood.

In addition to helping diabetic people fight their diabetes, the saponin content of sky fruit also offers the following benefits.

  1. Research published by the National Institutes of Health shows that saponin has anti-allergenic and antihistamine effects, making it a potent remedy for various allergy-related health problems, especially asthma.

  2. Research also shows that saponin can potently overcome erectile dysfunction, especially the one related to diabetes. Experiments on rats have shown that the administration of high dose of saponin to the rats successfully increase their intracavernous pressure ratio. Many herbs that contain saponin, especially ginseng, have been consumed regularly by men to improve their masculinity.

  3. Saponin is an effective cure for blood clotting and insomnia.

  1. Alkaloids

One of the greatest benefits of sky fruit seeds is that it alkalizes the body with its alkaloid content. It has been widely accepted that most illnesses occur when the pH level of the body is too low. Everything that pollutes the body, including toxins and free radicals, are acid in nature. The alkaloid content of sky fruit is thus effective for detoxifying the body and preventing oxidation and its damaging effects. The body will be healthier and fresher if it is alkalized. Alkaline environment is also a bad place for cancerous cells to grow. By consuming sky fruit regularly, the body will be more invulnerable to cancer and its immune system will significantly improve.

By looking into the health benefits of sky fruit’s active ingredients, you should be able to conclude what benefits that you can reap from regular sky fruit consumption. This explanation, however, is still limited to theoretical concept and so far, clues affirming the efficacy of sky fruit are solely based on anecdotal reports. Further researches on the fruit are needed to clarify the beneficial effects of this fruit as well as its side effects, which will be explained below.

Sky Fruit Side Effects

Due to the relative absence of conclusive research on sky fruit and its health effects, sky fruit seed side effects are currently as obscure as its benefits. There is indeed currently no consumer report telling that sky fruit causes side effects; however, based on established scientific theories, there are indeed unwanted effects that may occur if its active flavonoid ingredient is taken excessively.

According to a research published in Free Radical Biology and Medicine, flavonoid has a tendency to have mutagenic and genotoxic properties. At normal dietary dosage, those harmful properties will not be triggered and flavonoid will remain beneficial for its consumers. If taken excessively, however, this antioxidant will turn into a pro-oxidant and a mutagen. Excessive consumption of flavonoid thus will cause a backfire and will do more harm than good to the body. Regarding the mahogany seeds for a menstruation, we have not got the exact reference on the impact on health. Although there is currently no research on sky fruit that adopts this theory, it is better to be cautious when consuming the seed.
