One study examined 45 patients – both men and women – with known symptoms of peptic ulcers in the 16-60 age groups. 25 patients had gastric or duodenal ulcers. They were given 300mg of turmeric filled capsules 5 times daily, ½ to 1 hour before meals and at bedtime for 4 weeks. After 4 weeks, tests revealed that in 12 cases, the ulcers were absent and in 18 cases, further treatment for 8 weeks cured the ulcers. In 19 patients, the ulcers disappeared after 12 weeks. The remaining 20 patients did not have ulcers when tested. Instead they suffered from dyspepsia, gastritis and erosions to the stomach lining. They were given turmeric filled capsules for 4 weeks. Within the first 2 weeks, stomach discomfort and pain disappeared. They could also return to a normal diet. Hematological system, renal and liver functions and blood chemistry of all patients displayed no significant changes before and after taking turmeric capsules. Turmeric indeed did the trick here!
In another study, rats infected with H.pylori bacteria were given turmeric (curcuma longa). Their gastric acid secretion lessened and they did not develop gastric ulcers. This was believed to be because of the ability of turmeric to block H2 histamine receptors which then inhibited secretion of gastric acid and prevented formation of gastric ulcers. This strengthens ability of turmeric to fight harmful microbes.
