Natural Home Cures Mangosteen Xanthones Documented Peer Review Studies

Among the 56+ mangosteen xanthones found in the whole mangosteen fruit, alpha-mangostin and gamma-mangostin have been the main subject of many academic, medical and scientific studies by mangosteen researchers from around the world. These two mangosteen xanthones have been shown to be very useful as anti-inflammatory agents.

One research study revealed that the mangosteen xanthones were, even more, potent than several anti-inflammatory medications used for pain and inflammation. (Agricultural Food Chemistry - Bioavailability Antioxidant Effects Xanthone-Rich Mangosteen.)

The xanthones found in mangosteen are being demonstrated to reduce inflammation by inhibiting the body's production of the COX-2 enzyme and blocking the process that leads to inflammation. The xanthones achieve this without affecting the blood's clotting mechanism or damaging the stomach lining (causing ulcers) as most anti-inflammatory medications do. One study documented that the mangosteen xanthones helped with stomach ulcers. (PubMed - Role Of Gastric Mucus Secretion, Sulfhydryl Groups On Gastroprotection (Xanthones).)

Alpha-mangostin: a xanthone derivative from the mangosteen was found to have Anti-Cancer effects in their short-term colon carcinogenesis bioassay system. (PubMed - Anti-Cancer Effects Of Xanthones From Pericarps Of Mangosteen.)

In another study on alpha-mangostin's effects on human leukemia cells, results indicated Mangosteen Xanthones Extracts For Natural Anti-Cancer and Chemopreventive Therapy. (PubMed - Mangosteen Xanthones Extracts As Natural Chemopreventive Anticancer Drugs.)

Alpha-mangostin was also shown to have potent antibacterial activity against Staphylococcus aureus. Scientists demonstrated alpha-mangostin's activity against vancomycin-resistant Enterococci (VRE) and methicillin-resistant Staphylococcus aureus. They found that alpha-mangostin, alone or in combination with gentamicin, against vancomycin-resistant Enterococci (VRE) and used in conjunction with vancomycin hydrochloride against methicillin-resistant Staphylococcus aureus (MRSA) might be useful in controlling VRE and MRSA infections. (PubMed - Antibacterial Activity Of Alpha-Mangostin Against Vancomycin-Resistant Enterococcus.)

Researchers also found that alpha-mangostin is a histaminergic receptor-blocking agent; alpha-mangostin is effective in mitigating allergies. (PubMed - Mangosteen Xanthones Mitigate Ovalbumin-Induced Airway Inflammation Of Asthma.)

Gamma-mangostin: Scientists demonstrated that gamma-mangostin proved to be a stronger antioxidant than other compounds long known for their antioxidant properties. Medical researchers in Thailand and Taiwan discovered that gamma-mangostin was shown to have even more potent antioxidant activity than vitamin E, one of the most powerful antioxidants known to science. Even more than just being powerful antioxidants, gamma-mangostin may be able to help with a wide variety of common health issues. (Sigma - Aldrich - Gamma-mangostin.)

Oxidized low-density lipoprotein (LDL or "bad" cholesterol) is one of the main causes of atherosclerosis and heart disease. Australian scientists studied gamma-mangostin in experiments using LDL and powerful oxidants. Their study showed that gamma-mangostin successfully protected the LDL from oxidation by free radicals. (Toxnet - Mangostin.)

Scientists also demonstrated that gamma-mangostin limits the body's production of the COX-2 enzyme without causing ulcers. In fact, their study showed that gamma-mangostin even helped with stomach ulcers. (Memorial Sloan Kettering - Mangosteen.)

One study also suggested that the anti-inflammatory effects of gamma-mangostin on brain cells may have the potential in addressing inflammatory conditions of the brain. Alzheimer's is one example of these inflammatory conditions. (US National Library of Medicine - Multifunctional Effects of Mangosteen Pericarp on Cognition.)

About 150 million people worldwide have asthma, and about 40 percent of people in developed countries suffer from allergies. Several studies have shown gamma-mangostin as a possible natural antihistamine that can be used to address allergies such as asthma and psoriasis. (Drugs - Mangosteen.)

In another study, Japanese scientists found that gamma-mangostin is a 5-HT2A receptor antagonist in the central nervous system which indicates it has the potential for helping with depression and other anxiety symptoms.

The power of gamma-mangostin to help with a variety of health issues, as well as its unique anti-inflammatory properties, makes it one of the most admired xanthones in mangosteen. (PubMed - Gamma-mangostin, a novel type of 5-hydroxytryptamine 2A receptor antagonist.)

Scientists investigating the effects of the mangosteen xanthones on the HIV-1 virus found that mangostin and gamma-mangostin demonstrated the ability to inhibit the activity of the HIV-1 virus that causes AIDS. (PubMed: Active Constituents Against HIV-1 Protease From Garcinia Mangostana.)

Xanthones also have cancer-fighting properties. In one study, a xanthone from the mangosteen—Garcinone E—was found to be more effective than the chemotherapy agents fluorouracil, cisplatin, vincristine, methotrexate, and mitoxantrone with regards to lung, stomach, and liver cancer cells.
(Memorial Sloan-Kettering Cancer Center: Mangosteen)








Researchers found that alpha-mangostin, beta-mangostin, and garcinone B were strong inhibitors of Mycobacterium tuberculosis. Mangostin was also found to have the ability to protect the LDL from oxidative damage by free radicals. (PubMed: Mangostin Inhibits Oxidative Modification Of Human Low-density Lipoprotein.)

This helps in addressing the "bad cholesterol" (LDL) levels about (heart disease). Xanthones also have the ability to stop histamines that often cause uncomfortable inflammation in people with allergies. (PubMed: Inhibitions Of Histamine Release & Prostaglandin E2 Synthesis B Mangosteen.).
