Ascorbic acid (vitamin C) is a water-soluble vitamin. It occurs as a white or slightly yellow crystal or powder with a slight acidic taste. It is an antiscorbutic product. On exposure to light, it gradually darkens. In the dry state, it is reasonably stable in air, but in solution it rapidly oxidizes. Ascorbic acid (vitamin c) is freely soluble in water; sparingly soluble in alcohol; insoluble in chloroform, in ether, and in benzene. The chemical name of ascorbic acid (vitamin c) is L-ascorbic acid (vitamin c)

• Vitamin C is recommended for the prevention and treatment of scurvy.

Glycerol works by drawing water into the intestine through osmosis, which makes
the stool soft and easier to pass.
Glycerol is the pure chemical product and its commercial product is called glycerin.
Glycerin is needed to produce glycerol
Glycerol is a colorless, odorless liquid with a sweet taste. It is viscous at room
temperature and non-toxic in low concentrations.
Glycerol can influence immune reactions in the body through histamines,
increased antibody production and by enhancing immune cell activity and is
therefore classified as an allergen. In the blood, glycerol can increase blood pressure
by preferentially attracting the water from tissues into plasma and lymph. In
nephrons, glycerol can increase urine volume by preventing water resorption.

Suppositories of glycerol can act as laxatives since they can irritate anal mucosa.
Glycerol usage in the pharmaceutical industry is to improve smoothness and taste. It
is used in the creation of tablets so that they are easy to swallow. The coating can
disintegrate within the body. Cough lozenges often use glycerol to give a sweet taste.

Common side effect with the use of glycerol is dehydration

It is usually taken once a day as needed for up to 2 weeks. Take it exactly as
