The Processing Of Chinese Herbs: Herb’s Therapeutic Properties

The Processing of Chinese Herbs

The processing of Chinese herbs: herb’s therapeutic properties – often, in Chinese medicine, you hear the term “hot” or “cold” and “taste” as they apply to herbs and the response from people who take them.

The description reflects the herb’s therapeutic properties, and help guide practitioners to prepare a specific herbal formula that is needed for each person, known as personalized intervention. The herb can be warm, or bitter, or sweet, or other descriptive attributes.

Researchers say that preparing herbs is an extensive process that involves many layers of work. At the outset, impurities are removed. Then, there is “washing, cutting, drying as well as steaming and also stir-frying of herbal materials to increase solubility,” recent research in Chinese Medicine says. The process also includes “reducing unpleasant smells, reduce toxicity, decrease side effects, enhancing the pharmaceutical efficacy and stabilized and modify therapeutic property,” the research shows.

Importance of Processing

Processing also has a close relationship with a herb’s therapeutic ability. For example, the research adds, according to Chinese medicine principle, raw Rehmannia radix, a root common in Chinese medicine, is considered to have “sweet and bitter” with “cold” properties and can be used to treat “heat” the body for certain illnesses. But the processed Rehmanniae radix can have “sweet” and “warm” properties and can be used to treat “cold” syndromes. Those changes show the various possibilities for treatment with the Chinese herb or medicine.  While “cold” relates to chills, and body aches, “heat” refers to fever and inflammation.

Essentially, the chemical compounds can be changed by processing and then may induce different therapeutic properties. Almost all herbal materials are required to be properly processed before being used, research shows.

In China, there is a big demand for science-based protocols that are “fast, robust and sensitive measurements for evaluating the quality during and after the processing,” according to the Chinese Medicine journal.

Delayed Luminescence

One system being studied is known as delayed luminescence, which helps to categorize the properties of herbs during and after processing. It can be used to show differences of herbal materials prepared under different conditions, as well as the age of the herb and environment.

Delayed luminescence relates to the manner in which organisms have a “decaying emission” of light after exposure to light, or illumination, from microorganisms to leaves. With this process, food quality and seed germination, can be measured, and other properties of herbal medicine.

As a result, delayed luminescence, as it is being developed, provides a “promising technological platform for investigating the properties of Chinese herbal medicines, both qualitatively and quantitatively.”  Research adds that it may serve as a “robust and sensitive tool for evaluating the therapeutic properties of herbs base on the traditional Chinese medicine classification of various elements,” such as taste, according to Chinese Medicine journal.
