Many modern drugs are derived from purified and concentrated plant compounds (although compared to 20 years ago, few drug companies expend time and money looking at medicinal plant chemistry these days). Rosy periwinkle (Catharanthus roseus), for example, a perennial plant native to Madagascar, is the basis for a number of commonly used cancer drugs that have been in use since the 1960s.1
Of the 70 different alkaloids found in periwinkle, the two primary compounds used in anticancer drugs are the powerful vinca alkaloids2 vinblastine and vincristine.3Alkaloids are nitrogen-containing compounds shown to be very important for human health. Within the family of alkaloids, there are those with antiparasitic, antidiabetic, anticancer, antihypertensive and/or antiasthma properties, just to name a few. Others benefit your mood.
Even the humble daffodil contains a valuable alkaloid with anticancer properties called haemanthamine. This alkaloid inhibits the protein production cancer cells depend on to grow and flourish. Berberine is yet another powerful alkaloid found in plants such as goldenseal, goldthread, Oregon grape root and barberry. These plants have traditionally been used in the treatment of Type 2 diabetes, gastrointestinal infections, liver problems and a number of other health conditions.
Berberine is particularly beneficial for mitochondrial function and is a powerful activator of AMPK, a metabolic master switch. Interestingly, glyphosate — the most widely used herbicide in the world — robs the plant of the ability to make these important medicinal compounds.
