VS-C 100 Capsules is a traditional herbal blend with dandelion, purslane, indigo, bupleurum, scute root, typhonium, ginseng, cinnamon twig and licorice. The overall focus is immune support with added support for the liver and respiratory system, rather than one standout nutrient.
Dandelion, purslane and bupleurum are often used in traditional practice when cleansing and liver support are part of the picture, while scute root and typhonium are more closely associated with respiratory support. Ginseng and licorice help round out the formula. VS-C 100 Capsules is therefore best understood as a layered herbal formula for times when you want immune support with a broader traditional herbal base.
