There's a somewhat alarming development afoot in Canada relating to the sale, use and dispensation of herbal medicines and "natural" supplements. We've been following the discussion on herbal product regulation here in the United States, and looked briefly at the impact that Canadian legislation passed in 2004 (very similar to the FDA's current rules) and the impact it's had on herbalists.
Michael McGuffin, President of the American Herbal Products Association wrote an interesting counterpoint in response to an editorial in the journal Clinical Pharmacology and Therapeutics (full text for both should be available for all starting in April 08).
A large study conducted in Norway points at some definite links between headaches and GI tract complaints like acid reflux (see figure on the left), nausea, constipation, and diarrhea. Over 60,000 people participated, and the results were adjusted for sex, age, education, depression, anxiety and use of medication. The clearest connection was between headache frequency and GI symptoms (rather than severity, or simple headache occurrence). All reported symptoms were evaluated clinically (quite a feat!) and so there is some measure of objectivity to the data as well.
A nice article from Nature magazine shares some interesting research on the mycelia of mushrooms (the main growing part, usually underground, which produce the spore-bearing fruiting bodies we harvest and eat). We've known for a long time that mycelia are everywhere, almost saturating soil and contributing to the ecological balance of forest and field alike. We've even studied how some plants, like orchids for example, engage in a delicate balance with the root-like tendrils of fungal mycelia (known as mycorrhizae), benefiting in both nourishment and protection. Recent research has focused on how the web of fungal roots in the soil of the forest acts as a literal 'network', sharing and balancing resources between itself and different species of green plants. It seems quite likely, in fact, that many plants could not exist without their fungal symbiotes: but the story goes deeper than that."By proper Herbalism, I mean the variety practiced by Herbalists who have devoted many years of study to the application of herbs for medical purposes, as opposed to the fairy chasing brigade who hijack any therapy that they can practice with minimal effort..."
It's late August, the sun is still hot, the evening light is orange, and the Comfrey is still going crazy.
Sure, we all know that stress, tension and the anger that sometimes accompany them don't make us feel too good. A study from researchers at Duke, using data obtained by the Air Force, reveals just how linked these aspects of life are to crucial markers of cardiovascular inflammation. Elements (part of the complement family of proteins) in the blood that are involved in regulating inflammation in the heart and blood vessels seem to get overproduced by significant factors in men who feel more anger, hostility, and depression.
