Hi Aaron, Jerry, I have treated PMS using special diets, acupuncture and/or herbs, usually quite successfully. Sometimes I just use herbs. First, whether or not the fatty acids are responsible for the improvements is unknown. In TCM the herbs are taken for their energetic qualities, a set of properties/categorizations that were developed long before the current scientific paradigm became useful for identifiying active ingredients and chemical components that impact human health. I suggest people do not self-prescribe. Herbal prescription is complex; I am a bright person, had four years of training in school, and only after many more years of experience did I think I was adequately knowledgeable to competently create excellent TCM herbal formulas for illnesses. Second, all the reading I have done says that EPA, a type of omega3 fatty acid comes only from consuming fat fish or some flesh type marine life, or very fresh sea vegetables (the latter only has small amounts however, and dried, these oils are destroyed). Other omega3 fatty acids ARE present in some non-sea plants, but not EPA. These fats are used by the body in a number of ways but most importantly to make prostaglandin (hormone), a chemical item needed in small amounts for good health. These fats from fish are plentiful in bass, mackerel, salmon, tuna and other fat fish. As far as I know, no research is out on exactly how much is needed for (1) good health to prevent deficiency problems; or (2) optimum health. At least that is what Udo Erasmus' book clearly states, a fairly recent book. Apparently, in relative terms, this nutritional science has not been thoroughly researched, as, say most vitamins or minerals have been. regards roberta Jerry: > << I know they are in herbs, I have used them treating PMS, just dont want to > give you the wrong info. >> > Please let me know if you come across any information about this.
