I see in him one of the most eminent geniuses in the history of medicine. Many of his basic ideas have been adopted without having his name connected with them. Yet, he has achieved more than seemed possible under adverse conditions. He leaves a legacy which commands attention and which will assure him his due place. Those whom he has cured will now attest to the truth of his ideas.
“Over 80 years ago, Nobel Prize-winner Otto Warburg, M.D., Ph.D., proved that a 35% reduction in oxygen caused any cell to either die or turn cancerous. American experiments from 1953 to 1955 confirmed the result.”  This principle is at the center of the work that Dr. Seyfried is doing with the ketogenic diet as it is used for cancer treatment as discussed in the previous section.
Since herbs are food, there are generally no dangerous side effects of using them in there natural state. If they are herbal extracts, they are more potent then the raw herb and should be taken in smaller doses to get the desired effects. Some herbs have a cleansing and detoxifying effect on the body and can cause diarrhea and nausea if taken in large quantity. Don’t worry. It’s good to cleanse the body of toxins. Just start off slowly and you’ll get the best long term results.
In Europe, apothecaries stocked herbal ingredients for their medicines. In the Latin names for plants created by Linnaeus, the word officinalis indicates that a plant was used in this way. For example, the marsh mallow has the classification Althaea officinalis, as it was traditionally used as an emollient to soothe ulcers. Ayurvedic medicine, herbal medicine and traditional Chinese medicine are other examples of medical practices that incorporate medical uses of plants. Pharmacognosy is the branch of modern medicine about medicines from plant sources. Plants included here are those that have been or are being used medicinally, in at least one such medicinal tradition.
