Arginine is a semi-essential amino acid, which, with its derivative ornithine, stimulates the secretion by the pituitary gland of growth hormone in the brain. This is essential not only for children's growth, but also for adults, since it promotes repair of worn tissues and helps to heal wounds. In addition, it stimulates the growth of T-lymphocytes ­immune cells that identify, engulf and destroy invading bacteria and carcinogenic chemicals. In this respect, arginine can be extremely useful in the treatment of autoimmune diseases such as arthritis and multiple sclerosis. Arginine and ornithine have also been reported to stimulate weight loss and increase sperm count and motility. Supplemental arginine can raise nitric oxide level, a compound that increases blood flow and facilitates penile erection

Arginine is usually taken in doses of 2-4 g on an empty stomach, preferably at bed time, as peak secretion of growth hormone are released after falling asleep, or one hour before strenuous exercise. Caution: Arginine and ornithine should not be used by children or pregnant and lactating women. Arginine is contra-indicated in herpes.More recently, with the resurgence of interest in natural living and complementary medicines, aromatherapy has become increasingly popular. Around three thousand essential oils are used by trained aromatherapists, most of whom use a holistic approach, i.e. they do not treat merely the symptom, but consider the complete physical and emotional state as an entity. An essential oil may contain many different compounds, all working together to provide benefit.

Many aromatherapy blends are available which are carefully balanced to produce specific effects such as relaxation, sensuality, clarity and inspiration. For example, a sensual blend can be made from ylang ylang, lavender and sandalwood, while premenstrual tension can be eased with a blend of clary, sage and geranium. Essential oils are quickly absorbed, and inhalation is very effective for delivering the active ingredients to the bloodstream. Many essential oils are also very effective as antimicrobial and antifungal agents.
