Curing Cancer With Herbal Remedies

Cancer is a class of diseases in which a group of cells affectation the traits of uncontrolled evolvement (growth and division beyond the standard limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant properties of cancers differentiate them from kindly tumors, which are self-limited, do not invade or metastasize. Most cancers form a tumor but some, like leukemia, conclude not.
Curing cancer with herbal remedies - a case for shamans and herb women? Not at all, for many chemotherapies to fight cancer applied in modern medicine are natural products or were developed on the grounds of natural substances. Thus, taxanes used in prostate and breast cancer treatment are made from yew trees. The popular periwinkle plant, which grows along the ground of innumerable front yards, is the source of vinca alkaloids that are effective, for example, against malignant lymphomas. The fashionable anti-cancer drugs topotecan and irinotecan are derived from a constituent of the Chinese Jovial Tree.
Camptotheca (happy tree) is a genus of medium-sized deciduous trees growing to 20 m tall, native to central China. They are usually included in the tupelo family Nyssaceae, however sometimes included (with the tupelos) in the dogwood family Cornaceae. Camptotheca is used to make Irinotecan, Topotecan, 9-Aminocamptothecin, and camptothecin-1 (CPT-1). There are two species: Camptotheca acuminata Decne. Camptotheca lowreyana S.Y.Li.
Looking for new compounds, doctors and scientists are more and more focusing on substances from plants used in traditional medicine. Approximately three quarters of the natural pharmaceutical compounds commonly used today are derived from plants of the traditional medicine of the heads in various parts of the world. The chances of finding new substances with interesting working profiles in traditional medicinal plants are better than in common-or-garden botany.
In his search for active ingredients, Professor Dr. Thomas Efferth of the DKFZ has been concentrating on herbal remedies from traditional Chinese medicine with largely well documented application range. Working cool with colleagues in Mainz and Düsseldorf, Germany, Graz, Austria and Kunming in China, he launched a systematic compound search in 76 Chinese medicinal plants that are believed to be effective against malignant tumors and other growths. Fundamental results of this discover accept now been published.
"With this success proportion of about 24 percent, we are way above the results that could be expected from searching through doozer chemical substance libraries," Thomas Efferth said.
The scientists proceeded to chemically separate, step by step, all active extracts, tracing the active component after each separation step by cell tests. The chemical structure of the compounds is analyzed using nuclear magnetic resonance and bulk spectroscopy. "We are combining natural substance proof with contemporary analytical and molecular-biological methods", Efferth explains. "Plant constituents that seem particularly promising are immediately subjected to besides tests." Such constituents include, for example, substances derived from the Rangoon Creeper, an ornamental plant with chestnut flowers, or from Red-Root Sage. The latter contains three ingredients with powerful anti-tumor activity. The substances were found to suppress the growth of a specific tumour cell line that is particularly resistant to crowded commonly used cytotoxins due to overproduction of a transport protein in the cell wall. In contrast, a full range of standard anti-cancer drugs fail to be effective against this cell.
"We can expect to find many interesting, yet unknown working mechanisms among the chemically highly diverse general substances. Currently, we are aligning the effectiveness of the substances on 60 at odds cancer cell lines with the gene activity profiles of these cells. Thus, we can determine the exact gene products that are the cellular targets of our compounds. Thereby, it may be possible to announce solid new Achilles' heels of the cancer cell," said Efferth describing the abutting steps.
