Derived from the bark of African evergreen trees is the widely used herb yohimbe. The herb was used as an aphrodisiac and traditional remedy for sexual enhancement, used in marriage ceremonies and fertility festivals. Today the herb is used to treat erectile dysfunction, sold in both prescription strength and over-the-counter formulas for male enhancement. As an over-the-counter dietary supplement, extract of the bark is put into capsules and tablets. However, some yohimbe products contain insufficient amounts of the extract, making prescription options a better choice. Side effects can be serious, resulting in high blood pressure an increased heart rate, according to the National Center for Complimentary and Alternative Medicine >>>>>>http://sexuallubricants.org/sexual-lubricants/
