i am concerned about my friend Margot, who is extremely obese and cannot reach her feet, nor lower legs. They are covered with fugus. Her doctor, who practice traditional, as well as Chinese herbal, gave her an herb, which helped for a short while, but it made her ill. He gave her cream to put on the feet and under breasts, etc., but the lower part of the body, she can't reach. It is making her depressed. I thought perhaps she needed an antibotic, in addition to a tropoical medicine. Is there a home remedy that would help? I am trying to get her help with someone who can put the medcine on feet and legs. Thank you. Louise
