Edgar Cayce recommended a tablespoon of Glycothymoline (watered down) three times a day to alkalinize the body to lessen allergic reactions. I know it's quite unconventional, but Cayce's remedies has worked wonders for decades for many people. If you decide to give it a shot, make sure you buy the original Glycothymoline (yes, it's a mouthwash) and take it for several days before trying to introduce any allergens to your body. Best of luck! Keep me posted on your success!
