Soy Lecithin- Although lecithin is a word that is derived from the Greek "lekithos" that translates to "yolk of an egg", the biggest source of lecithin is in fact soybean. Lecithin is nothing but a combination of phospholipids that are naturally present in soybeans and is thus an excellent source of choline. In the absence of choline, the cell membranes are bound to become hard preventing any kind of nutrient exchange. Soy lecithin powder can be easily incorporated into your culinary and body care recipes since it acts as an emulsifier, thickener, mild preservative, emollient, moisturizer, and stabilizer. For the same reason, it is used in food as well as cosmetic products alike. Lecithin also plays an important role of moving cholesterol through our bodies and its ability to bind chemically with cholesterol actually helps in reducing cholesterol levels. It also helps in treating neurological disorders, psoriasis, gallstones, diabetes, and anemia.

Yohimbe- Basically a tree bark, Yohimbe is rich in pharmacologically active chemicals. It is commonly found in products developed for body building and enhancing male performance. The use of Yohimbe causes serious side effects too that include renal failure, seizures and in very rare cases, even death. Individuals suffering from low blood pressure, heart disease, liver or kidney disease, and diabetes should refrain from using any kind of Yohimbe supplements. Taking larger doses of Yohimbe can cause weakness, stomach disorders, fatigue, and nervous stimulation followed by paralysis. It is therefore important to avoid self-medication. Sometimes, side effects may arise even if small amounts of this supplement are taken, especially for prolonged periods. If you are already taking drugs for treating some health condition, it is best to avoid this supplement.
