China-Oel contains 100 percent pure essential oil of peppermint. It is extracted by steam distillation from the aerial and flowering parts of the plant and is subject to constant pharmaceutical control. The cooling effect during application results from the interaction of menthol with the skin's cold receptors. It is recommended to inhale, consume or use for massage as needed: In case of inhalation: put 3 to 4 drops in hot water and inhale with eyes closed. It can also be inhaled with the convenient China Oel inhaler without water. In case of consumption: take 3 to 4 drops (max. 0.12 ml) in lukewarm water. In case of massages: use 2 to 3 drops on the chest or back (for coughs and colds) or in the appropriate place (for muscle pain). China-Oel for internal and external use is indicated only for adults over 18 years of age, inhalation also for adolescents over 12 years of age. Peppermint oil (internal use) should not be taken if you are allergic to peppermint oil and/or menthol or if you have liver disease, gastric acid deficiency, biliary inflammation, gallstones, or other bile conditions.
