Aromatherapy is a dynamic healing modality that works at a cellular, molecular level as well as on an emotional, psychological level. Physically, it can be used as an immune stimulant to prevent infection and to mitigate symptoms of infectious disease. Aromatherapy is the therapeutic use of essential oils, whether absorbed via the skin, the olfactory system or taken internally. When essential oils are taken internally, the therapy becomes part of herbal medicine, not aromatherapy. Essential oils are produced by steam distillation of plant material or cold expressions from citrus peel.
Essential oils are extremely complex and are made up of many different chemical components.
The immune system is also an amazing, complex group of cells that are there to protect us from invading pathogens. The immune system has the ability to distinguish self from other. Sweat, sebum, and mucous membranes all have a pH balance and some white blood cells to discourage and cleanse bacteria from entering internal passageways. An aromatherapy treatment to strengthen the skin's defense would be a friction. Rub between your hands quickly and apply to your chest, stomach and thighs.
