A Yours is just one of many queries I have received on this subject. The ideal relative humidity in a British home is around 50 to 55 per cent.
Psyllium is a soluble fiber used primarily as a gentle bulk-forming laxative in products such as Metamucil. It comes from a shrub-like herb called Plantago ovata that grows worldwide but is most common in India. Each plant can produce up to 15,000 tiny, gel-coated seeds, from which psyllium husk is derived.
Veterinarians often recommend psyllium for use as a laxative, specifically for clearing sand out of horses' intestines to minimize the chances of sand colic. But new research indicates there might be another use for the phytogenic (plant-based) supplement: the control of blood glucose and insulin concentrations. Research performed in humans indicated that oral psyllium supplementation reduced blood sugar and insulin response after eating, but psyllium's effects on horses' blood glucose and insulin levels had not previously been examined.
