I have seen many people have outstanding results with asthma using high quality OPC.
This is information from a study that was taken from Dr. Dwight McKee’s blog where the people got results using a small amount of OPC:
“A clinical trial done at the Chieti-Pescara University in Pescara Italy, published in the Sept 2011 issue of Panminerva Medica, showed that a surprisingly small amount of a standardized oliogmeric proanthocyanidin (OPC) extract of French Maritime Pinebark (Pycnogenol®, produced by Horphag Research), made a very significant difference to a group of chronic asthma sufferers, who were already being treated with inhaled corticosteroids. You can read the abstract here. One group received only 50 mg of the OPC concentrate twice daily, while continuing their inhaled corticosteroids, whereas the control group continued to receive only inhaled corticosteroids. It has previously been shown that OPCs decrease expression of an enzyme that produces highly inflammatory fatty acids called leukotrienes, which are known to mediate bronchial muscle inflammation in asthma. Over the 6 month period of the study, nearly 20% of the control group required an increase in the dose of inhaled steroids to keep their asthma under control, whereas none of the Pycnogenol group did. In fact, in the group taking the OPC supplement, 55% of them improved enough that they were able to lower their dose of inhaled steroids, vs only 6% of the control group that was able to lower their inhaled steroid dose.” To see the rest of the blog post go to: http://www.dwightmckee.com/2012/11/08/nutrition/standardized-opc-extract-of-french-maritime-pinebark-clinically-useful-in-asthma-management/
My experience has been that twice your body weight in milligrams of pure OPC (for example Lifeplus Proanthenols) makes a huge difference. It is safe and water soluble and has no interactions with any medications. This is the same nutrient that has also helped me and many others with allergies.
