Neem is a plant that grows in India and the Middle East. It has been used in Ayurvedic medicine for many years to treat for fungal, bacterial, and viral infections. It should be taken with food, as it lowers blood sugar and can drive levels too low if taken on an empty stomach. Because of its antifungal and antibacterial component, it often shows up in shampoos and hair care products.
Neem is rich in antioxidants so it can stimulate the liver and kidneys to help eliminate toxins quickly. It is often applied as a paste on the face/skin or consumed as a supplement to help with detoxification (much like activated charcoal). Also, since neem is rich in essential fatty acids (like oleic acid and stearic acid etc.), triglycerides, Vitamin E, and calcium, it is showing up in more and more skincare products as all these nutrients hinder the oxidization process as well as may stimulate collagen production (since collagen goes down with age resulting in wrinkles and loose skin) which improves the skin’s elasticity.
Neem is sold in the US as powder, tea, leaves, and oil. As with Amla, neem products like neem powder are slowly expanding to the US. The reason it isn’t everywhere is because it is hard to find organic, it has to be imported, and there is tremendous crop-to-crop variability due to where it is grown, resulting in difficult standardization in terms of nutrient levels. Nonetheless, it is another ingredient to keep an eye out for.
