Clove is an herb. People use the oils, dried flower buds, leaves, and stems to make medicine. Clove is used for upset stomach and as an expectorant. Expectorants make it easier to cough up phlegm. Clove oil is used for diarrhea, hernia, and bad breath. Clove and clove oil are used for intestinal gas, nausea, and vomiting.
Excretion. Excretion is the process by which waste products of metabolism and other non-useful materials are eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell.
In mammals, excretion is the formation of urine in the kidneys, and expelling carbon dioxide from the lungs. These waste products are eliminated by urination and breathing out respectively. If excretion does not occur in an organism, waste products accumulate, which eventually kill the organism. Also, food waste is expelled through the anus. Other substances are secreted into the bile, and then eliminated in the faeces.
