Your husband should mix one teaspoon of Epsom Salt with one teaspoon of vitamin C in powder (can be found in a health food store)in a glass of warm water and take it first thing in the morning. It tastes gross..
Or he can try the warm water or cammomile enemas every or every second day. He can buy a little plastic bottle for administering enemas in every shoppers drug mart and fill them with water or tea at home(rectal usage).
