White blood cells, or leukocytes are cells of the immune system involved in defending the body against both infectious disease and foreign materials. They are produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. They live for about three to four days in the average human body. Leukocytes are found throughout the body, including the blood and lymphatic system.

Motion sickness or kinetosis, also known as travel sickness, is a condition in which a disagreement exists between visually perceived movement and the vestibular system’s sense of movement. Depending on the cause it can also be referred to as seasickness, car sickness, simulation sickness or airsickness. If the motion causing nausea is not resolved, the sufferer will usually vomit. Ginger is reported to calm the pyloric valve located at the base of the stomach. This relaxation of the valve allows the stomach to operate normally whereby the contents will enter the small intestine instead of being retained within the stomach. It is this undesirable effect of retention in the stomach that eventually results in vomiting.

A balanced diet means getting the right types and amounts of foods and drinks to supply nutrition and energy for maintaining body cells, tissues, and organs, and for supporting normal growth and development. Milk is not considered a balanced diet as it lacks iron and some vitamins like Vitamin C. Calcium, phosphate, magnesium, sodium, potassium, citrate, and chlorine are all included as minerals and they typically occur at concentration of 5–40 mM.

Cloves are the aromatic dried flower buds of a tree in the family Myrtaceae, Syzygium aromaticum. Cloves are native to the Maluku islands in Indonesia and used as a spice in cuisines all over the world. The English name derives from Latin clavus ‘nail’ (also the origin of French clou and Spanish clavo, ‘nail’) as the buds vaguely resemble small irregular nails in shape.

Conjunctivitis is inflammation of the conjunctiva or thin membrane covering the white of the eye and the inner surface of the eyelid. The inflamed conjunctiva will usually make the eye appear red or pink because the tiny blood vessels that are normally within the conjunctiva are now irritated and enlarged. The white of the eye (sclera) is covered by a thin, filmy membrane called the conjunctiva which produces mucus to coat and lubricate the surface of the eye. It normally has fine blood vessels within it, which can be seen on close inspection. When the conjunctiva becomes irritated or inflamed, the blood vessels which supply it enlarge and become much more prominent, and the eye turns red.
