CHAPTER 1
PROBLEM AND ITS BACKGROUND
INTODUCTION
Oregano is a plant that grows from 20–80 cm tall, with opposite heart-shaped leaves 3 to 9 cm long. Oregano flowers are purple, 3–4 mm long, produced in erect spikes. It is sometimes called wild marjoram. Oregano leaves and flowers are used as antiseptic for cuts and burns. Oregano contains thymol, a crystalline substance that has antiseptic and fungicide properties. The primary germ-killing part of oregano oil is a substance called carvacrol. Oregano is a traditional herb that has been used for thousands of years for natural immune support. New science continues to prove its broad power to be of help. Oil of oregano is known to be a rich source of the volatile oils thymol and carvacrol, which have been shown to be largely responsible for enabling oil of oregano to kill various microorganisms under experimental conditions.
A dishwashing liquid is to remove stains, loosens food remains enough so you can wipe it away with little effort, to kill bacteria that sticks in the container. It is a detergent used to assist in dishwashing. It is usually a highly-foaming mixture of surfactants with low skin irritation, and is primarily used for hand washing of glasses, plates, cutlery, and cooking utensils in a sink or bowl. The reduced surface tension of dishwashing water, and increasing solubility of modern surfactant mixtures, allows the water to run off the dishes in a dish rack very quickly. However, most people also rinse the dishes with pure water to make sure to get rid of any soap residue that
