The gum of the Myrrh tree works with the thyroid gland to repair eyes and olfactory, which is the nose/throat cavity (taste/smell). Extract of myrrh is strongly anti-viral in nature (with anti-fungal properties as well). Indigenous to Africa and Arabia ancient Egyptians used it for asthma, blood purification, mouth sores, ulcers, nervous disorders and inflammation to tissue. It is a most excellent immune booster (i.e. AIDS sufferers) and can clean up infections, abscesses, and gum loss in the mouth, relieving tooth aches and pains. Internally it is especially good for Thrush (oral yeast infection) and Candida (intestinal yeast infection), it has anti-cramping properties, as in menstrual and intestinal cramps, and can be used topically for vaginal yeast infections.
