Oral capsules are used for the consumption of medications, herbs and vitamins. They help to deliver substances to the body via the digestive system. Many of these medications are bitter or unpalatable, so the capsules conceal the offensive product from the perceptive areas of the subject’s tongue.
Capsules may contain powders or pellets, and they may come pre-filled or empty. Empty capsules can be purchased and filled with many types of dry materials. The ends of the capsule are separated and the substance is placed inside. Machines are available for home use to fill multiple capsules at once.
