BRANDON - Forgive Vicki Parsons if she gets a little excited talking about neem. Parsons and her business partner, Jerry Britner, are the nation's only growers and importers of certified organically grown neem trees. The problem is, not a lot of people in the United States know about neem - yet. But Parsons says initial interest in neem from the cosmetic, medicinal and pesticide industries is promising. ``Interest in the product and its benefits are growing every day,'' Parsons, 48, said last week. Neem is a member of the mahogany family and is one of the most widely used herbs in the world, though relatively unknown in the United States. It can grow to 60 feet tall, spreading like an oak. In bloom neem has honey-scented white flowers like a locust tree. Fans are so loyal because every part of the neem tree - leaves, oil and bark - can be used for products including medicines, pesticides, soap and beauty products. According to a report by the U.S. National Resource Council - which advises government and the public on topics of science, engineering and medicine - neem can cure athletes foot and head lice, and relieve pain and fevers, among other illnesses. A few years ago, the National Institutes of Health reported encouraging results from tests to see if neem can block the AIDS virus Many people around the world, including Parsons, feed neem to their pets to cure digestive problems, eliminate mange and alleviate other ailments.
