Chinese herbal medicine has been documented since at least the 3rd century BCE. Its long practice has been studied and refined over time with modern scientific research currently also supporting its role as an important remedy in the treatment of human ailments. The most characteristic attribute about this particular form of herbal medicine is in its formula composition. Herbs are not administered on their own, but in combination, where the herbs interact synergistically producing an overall therapeutic effect. This method along with the Chinese medicine diagnostics gives rise to a very sophisticated system of healthcare. An herbal medicine consultation involves the taking of an in-depth medical history, detailing your current condition, pulse and tongue diagnosis. Herbal formulae are prescribed in granules that are dissolved in hot water and drank. A course may last a few months, or have a short duration and quick response for acute conditions. Formulae may be modified through-out to adapt to changes that occur during the treatment.
