Melatonin Side Effects
Melatonin has been used to ease insomnia, combat jet lag, protect cells from free-radical damage, boost the immune system, prevent cancer, and extend life.
The use of melatonin in cultural and traditional settings may differ from concepts accepted by current Western medicine. When considering the use of herbal/health supplements, consultation with a primary health care professional is advisable. Additionally, consultation with a practitioner trained in the uses of herbal/health supplements may be beneficial, and coordination of treatment among all health care providers involved may be advantageous.
