Months ago I found a site that explained how to replace Ibuprofen with a natural remedy to pain, such as a headache:
Bromalain: go with 1,800-2,400 (MCU) or 1,080-1,440 (GDU); take 500 mlg a day, 3 times, between meals;
Ginger: antioxidant - (tincture or capsule) for serious pain: 6,500 mlg (concentrate extract);
Vitamin C: (pain prevention) 2,000 mlg every day;
Vitamin E: 400 international units;
Siberian Ginseng: helps adrenal glands produce more stress hormones.
