Legendary Oriental Elixir of Life said to possess fantastic rejuvenating properties. Some believe fo-ti was used by a certain Professor Li Chung Yun who lived to the ripe old age of 256! So the story goes, early in life Li developed the penchant for taking a daily concoction containing the elixir of life. He is said to have outlived 23 wives, and left behind 11 generations of descendents when he died in 1933. Virility- and longevity-promoting prowess aside, fo-ti is one of the most widely used tonic herbs in traditional Chinese medicine. Roots are used to restore blood, liver and kidneys, and is prescribed for conditions as varied as vertigo, insomnia, lumbago, and constipation. Recent evidence shows it to be effective against high blood pressure and hardening of the veins and arteries. Climber.
