Mucilages and Gums (Polysaccharides): Widely
present in the plant kingdom these substances are hydrophilic, being able to
attract and bind with a volume of water that far exceeds the mass of the gum or
mucilage. Apart from their propensity to attract
water, Mucilages and Gums are virtually inert and also almost fully indigestible.
Generally the small amount of digestion that happens extracts very little sugar and no
noteworthy pharmacological effect. Because of
this neutrality and indigestibility their value if ingested is that they are
demulcent - which means that they coat and protect the lining of the gastric
tract, if applied externally they are emollient - which means that they coat and
protect the skin. |
