About Our Products

www.hyy.com.hk is an ancillary part of the Integrated Chinese Medicine Holdings Ltd. (ICM) that provides Chinese medicine herbal supplement products under its brand name of HYY (House of Yin Yang). The products are manufactured in certified GMP plants that undergo quality control in their production. Part of this process includes heavy metal and microbial testing for contamination of all products.


HYY stands for the “House of Yin Yang.” In Chinese medicine and Chinese culture, yin and yang represent the dynamic change and balance of the universe and the human body. Yin and yang theory illustrates how our bodies continually strive for a healthy balance that creates wellness in all aspects of our lives. HYY products are designed to be used by individuals to promote wellness and for general health maintenance. These products work subtlety to help restore our body’s natural balance so that it can function properly. When our body functions normally, it can then prevent us from getting sick.


The definition of wellness from a Chinese medicine perspective will vary from person to person as it is not defined by curing illness but rather by getting to a state where a person can function comfortably in their everyday lives. Chinese medicine practitioners believe that to restore the body’s health, it should be a gradual process of fine tuning our organ functions to achieve a healthy working balance. As with most Chinese medicine products, the health benefits that are to be derived from HYY products are usually felt within one to two months of taking a herbal supplement. Our company believes “health is wealth” and HYY products are designed to help individuals experience this.

Why are our products different?

The products of HYY use herbs that have been used in Chinese Medicine for centuries. Unlike products, which just use raw herbs, we identify and extract select herbs then combine them in our products for maximum efficacy. The main active ingredients are identified and monitored when possible using HPLC methods and measured against a predetermined chemical profile pattern that meets the company standards. In this way, quality assurance can be measured objectively along with heavy metal and microbial testing which helps to provide batch-to-batch consistency and ensure safe consumption.


We support ongoing research to further identify active ingredients in our herbal extracts so that quality can be continuously monitored and upgraded. Efficacy of our products is determined using Chinese medicine principles, practices, and research in combination with modern Western research techniques. Each herbal formula is based on traditional prescriptions and created with the expertise of TCM physicians.


It is only recently that modern research techniques have been employed to identify active ingredients responsible for health benefits of Chinese herbs. Therefore, many herbs’ active ingredients still have not been identified. It is important to recognize that HPLC testing only provides a chemical fingerprint of the active ingredients and their amounts found in particular herbs and does not measure efficacy of any herbal supplement product. This type of test is routinely employed in the herbal supplement industry to standardize herbs contained in a particular formula.


Chinese medicine practitioners have long recognized it is the combination of herbs and their active ingredients that work together to achieve health benefits. Therefore, measuring efficacy of Chinese medicine herbs must take into account how these herbs work together from a Chinese medicine point of view as well as a Western one. Our company is committed to undertaking this sort of research and we currently have ongoing research projects in China, Hong Kong, and the US addressing these issues.
