The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

Legends, Myths and Stories

The American pioneers learned about this versatile herb from Native Americans. Containing a powerful antioxidant, nordihyroguaiaretic acid (NDGA), Chaparral can be applied directly on wounds and injuries. Antioxidants inhibit the formation of dangerous substances in the body called free radicals, which disrupt normal cell function. Free radicals combine at random with components of healthy cells and interfere with normal cell growth. Free radicals are believed to be responsible for certain types of cancerous tumors and premature aging. Antioxidants prevent free radicals from doing their damage, thus helping to slow the growth of tumors and perhaps even retard the aging process. A biochemist of Louisville, Kentucky, who tested the effects of NDGA on female mosquitoes, reported that he was able to double their average life span from 29 days to 45 days. This herb also helps the body ward off infection, fights parasites, and is useful for urinary tract infections and diarrhea. An anti-inflammatory, Chaparral also relieves pain and swelling caused by arthritis and rheumatism.

In 1967, after 3 previous surgically removed growths, an 85 year old man refused further medical treatment on the 4th similar growth, documented to be malignant melanoma. He favored “Chaparral tea”, an old Native American remedy. He drank 2-3 cups of this tea every day. Eleven months later he was re-examined by medical professionals caring for him previously. They found the growth had decreased from the size of a large lemon to that of a dime. No other medication was used, only the Chaparral tea. In that 11 months he gained a needed 25 lbs., with improvements in general health. Previous to the Chaparral tea treatment, he was pale, weak and lethargic.
