However I can touch on a few suggestions to help get things on the right track. Allergy symptoms can be troublesome and often show up as itchy skin. If the itching is severe then Chinese herbal complexes called Zaocys and Xanthium 12 are extremely helpful in reducing irritation. Often, in chronic allergies or when there has been a history of drug use, the body's adrenal function is stressed and thus compromised. By giving a glandular nutritional supplement called Adrenal Complex this helps the body pick up the nutrients it needs to heal.
Any allergy is a sign of a weakened immune system which needs to be supported.
This can be helped with the supplements mentioned for mange. Additionally Pycnogenol is excellent in helping to reduce histamine production while increasing the bioavailability of vitamin C. Pycnogenol is made from Pine Bark and has been a long favored anti-oxidant in Europe. I use Pycnogenol from Da Vinci Labs. In place of using serum injections of the antigens, homeopathy can be used with excellent results. The antigens are made into homeopathic remedies called allersodes and are given to the patient orally.
