A naturopath from Western Australia informed me she had successfully treated seven patients with Crohn's disease, a chronic condition that causes damage to the intestines - with oral wheatgrass extract. She was also using the extract to treat common complications of the disease such as anal fissures and fistulas. They had all healed.
Considering there are no pharmaceuticals available that can achieve such results, that was quite an achievement .
I recommend taking just half a teaspoonful (or half a capful) of wheatgrass Supershots just twice a week - say Mondays and Thursdays, hold the liquid in your mouth for half a minute before swallowing - and persevere.
It often works well.
