CHOLINE - Controls fat and cholesterol buildup. Helps regulate the kidneys, liver, and gallbladder. Important for nerve transmission and helps improve memory. It has been reported that no cell in the human body could function normally without choline. One contention is based on the fact that choline is used by nerve cells to manufacture a closely related chemical called acetylcholine. Acetylcholine allows nerve cells to communicate with each other; if there were no acetylcholine in your brain, you wouldn't remember who you were. And how do nerves tell muscles what to do? They push small quantities of acetycholine across tiny spaces called neuromuscular junctions. When enough acetylcholine attaches itself to the outer surface of a muscle cell, the muscle cell becomes excited enough to contract. The penis is a basic muscle that needs blood to become erect. Choline may be the herb that assists the penis muscle to contract. - Source: U. S. Food and Drug Administration et.al.; Article: Owen Anderson; University of North Carolina.

It increases blood flow (no increase in blood pressure) in the genital area in both men and women. The Chinese call it Yin-Yang because of the increase of sexual pleasure it creates. Epimedium actually lowers blood pressure by dilating capillaries and blood vessels while slowing the adrenal production that can hinder blood flow to the sex organs. Men achieve better erections due to this effect. - Source: Chinese Academy of Sciences.

CINNAMON BARK - Medicinal use of cinnamon bark was first recorded in Chinese formularies as early as 2700 B.C. Cinnamon Bark helps the body to process food by breaking down fats during digestion. Efficient digestion promotes absorption of benefits of the other herbs contained in Sutrapryl. Since stomach acids may have a tendency to destroy some of these herbs, cinnamon may have a calming effect to allow a better absorption rate into the blood stream. The plant's essential oil has been found to stimulate movement in the gastrointestinal tract which may tend to assist also in the intestinal absorption. Cinnamon is also reported to have all these properties: anti-diarrhea, antidote to poison, aphrodisiac, antiseptic, antimicrobial, astringent, antispasmodic, antitoxic, bactericide, diuretic, antifungal, insecticide, tonic, immune stimulant. - Source: Personal Health Facts
