A San Francisco clinic states what many women already know: pot is quite effective in treating cramps, PMS and other menstrual issues as well as helping women with eating disorders:
Many women come to Greenway Medical Marijuana Physician Evaluations seeking help with ailments that only or primarily affect women, such as eating disorders, menstrual cramps, premenstrual syndrome (PMS), mood swings and menopause. The San Francisco medical marijuana doctors at Greenway Medical Marijuana Physicians Evaluations know that properly administered medical marijuana can provide relief, and they are seeing an increase in female patients.
Women who have developed eating disorders such as anorexia nervosa may find relief in the use of certain medicinal cannabis strains that aid relaxation, alleviate anxiety and stimulate the appetite. The naturally occurring marijuana compound tetrahydrocannabinol (THC) is known for improving desire for food and thereby helping patients gain weight. Strains high in THC are more likely to stimulate the appetite.
For many women, monthly menstrual cycles include cramping, and they can also include nausea and backaches. Cannabis is prescribed for cancer patients specifically because it helps target pain and nausea, so it follows that it would also be a good herbal remedy for cramps. Medicinal marijuana also has many secondary, non-psychological effects on the body, including the relaxation of smooth muscles that may be causing the cramps. Indica strains would be beneficial both prior and during the cycle.
