Honduran herbalist and healer, Dr. Sebi, says that iron is the spark plug of the human body. It is magnetic and has a tendency to attract other minerals to it. With this in mind, it’s no surprise that Sarsaparilla root holds the highest concentration of iron among all plants and contains so many other minerals too. This root can be used for sexual issues, impotence, colds and flus. Dr. Sebi recommends individuals take 1-2 capsules 3 times a day.
