Medical and Spiritual Qigong (Chi Kung)
Do not try to adjust your coumadin dosage by yourself. Do not experiment with this. The results could be disastrous. You need a skilled practitioner helping you with this situation. I would contact a nutritional pharmacy such as http://www.willner.com or http://www.invitehealth.com.There are contact points on these sites. I would ask to speak with a pharmacist or nutritionist. Outline your situation. Get a referral. You are still young. This is the time to take action. Good luck.
