Many women with cervical dysplasia have a folic acid deficiency

CERVICAL BUMPS: You can treat the problem cells and at the same time stimulate your immune system with a tea or tincture of echinacea, calendula and false indigo, an immune system herb with properties similar to echinacea. While most people may not think of calendula (which is known to gardeners as pot marigold) as more than a pretty garden flower, it is a potent immunity builder that seems to have a special affinity for healing the cervix.
You can also put herbs directly on your cervix—as Nancy did—by using vaginal suppositories or a tampon soak of goldenseal, calendula and tea tree.
Folic acid, which is not an herb per se but is found in green, leafy vegetables, can also play a role in treating cervical dysplasia.

Many women with cervical dysplasia have a folic acid deficiency, especially if they take birth control pills. According to one study of women on the Pill, three weeks of folic acid supplements reversed the risk of cervical cancer for a significant number of women. Joseph E. Pizzorno, N.D., and Michael T. Murray, N.D., authors of A Textbook of Natural Medicine, a natural healing reference commonly used by naturopathic doctors and medical doctors who use natural methods, suggest that women who have cervical dysplasia take 2 milligrams of folic acid a day for three months, then reduce the dose to 0.5 milligram a day. Along with your herbal therapy, vitamins A, C and the B-complex can be extremely helpful.
take these herbs once a day for one week every month to prevent the dysplasia from returning.
