Xi Shu (Camptotheca acuminate) is also known as Cancer Tree, Happy Tree, Heaven Tree, Dragon Tree, and Tree of Joy. Native to China and Tibet, most American specimens of the plant originate from just two seeds germinated here in the 1930’s. Xi Shu is used in herbal medicine for treating cancer, psoriasis, diseases of the liver, gallbladder problems , and stomach problems.
The plant is known to be effective in the treatment of rectum and large intestine cancer. Xi Shu can inhibit cell division and DNA replication which can slow tumor growth. Many other anticancer medications are derived from Xi Shu and two are approved by the U.S. Food and Drug Administration. Topotecan is used to treat ovarian and lung cancers. Irinotecan is used to treat metastatic colorectal cancer. Xi Shu may prove to be a lifesaver for thousands of cancer patients around the world. Currently, manufacturing of these two FDA approved anti-cancer drugs continues to depend on extraction from plant materials that are primarily harvested from naturally grown trees.
Xi Shu is currently being tested for applications in HIV / AIDS treatments. The plant shows promise in clinical trials.
This fast-growing, attractive “Happy Tree” of northern China is currently being grown at Louisiana State University's (LSU) Agricultural Center's Experiment Station. The expense of extracting and shipping medicinal Xi Shu compounds from China averages $35,000 per kilogram, but LSU researchers hope to cultivate the tree in Louisiana where 5,000 trees have been grown successfully so far. (LSU researchers see this as a model for a program to research other medicinal plants.) Xi Shu trees are also being grown in Texas.
Medicinal compounds are especially concentrated in the young, developing leaves and may actually poison livestock due to the high level of active ingredients. The herb can be purchased in various forms and is often an ingredient in over-the-counter Chinese medicines.
Xi Shu is a slender tree that grows up to eighty feet tall. The attractive tree has small, white flowers that mature into small fruit in summer. Xi Shu grows extremely fast in warm humid zones. The tree likes sun and moist, rich soil. Xi Shu is easily grown from seed.
* Xi Shu is toxic when taken in large doses. Xi Shu is generally regarded as safe, but use of this herb for treating cancer should be done under the supervision of a physician. Safety in young children, pregnant or nursing women, or those with severe liver or kidney disease is not known. Always consult with a physician before using any herbal remedy.
"The only way to really learn about herbal medicine is to touch and smell herbs, taste them, use them daily, and grow them if possible. Herbal medicine is a way of life. It is not a quick fix." ... Janice Boling, herbalist, web designer, writer, photographer
