Twelve percent of flax seeds is mucilage which makes it a gentle, non-irritating, natural laxative. Flax mucilage is perfect for those who have a sensitive stomach, acting as a buffer for excess stomach acids, soothing ulcers or irritable bowel disorders. Flax expands 20 times in volume and should be taken with a generous amount of water.
Flax seed slowly releases its mucilage through the fiber wall. After half an hour of soaking the little seeds, a slippery mucilage forms. The flax seeds act as a tiny mucilage release capsule. This release continues, changing the water to a slippery consistency similar to a light oil. Flax seed is God’s gift for a toxic colon! It lubricates and absorbs toxins perfectly.
Flax mucilage helps to prevent toxic build-up in the bowel during fasting or a healing diet. When juice fasting, take a teaspoon of whole flax, 2-3 times per day, with a generous supply of water. Do not chew the seeds; swallow them whole with a glass of water. This will allow only the mucilage to escape. The flax seed will pass out of the system without releasing any of its oil. Even though the oil is highly nutritious, it can hinder the deep cleansing process that is desirable during juice fasting.
