Lactulose
"Hubby is having chronic constipation. Many of us will when approaching 90. He used and still uses Casgara Sagrada (which never loses its potency. You don't have to take more and more.) This lactulose seems to work for him when he takes it regularly. He is also now taking two tablespoons of ground flaxseed stirred in 8 oz. of liquid daily. I do not have constipation now although I did as a child mainly from poor diet and not drinking very much water. A former mother-in-law religiously chewed a few slices of apple with some stewed prunes every night before bed. I understand that now she is 102. What a surprise!."
