Most people are familiar with the term "Let food be thy medicine and medicine be thy food". However, how much of modern day medicine is food ? How often do people with health issues seriously look into "medicinal/therapeutic foods" and to what choice is there in the modern Western cuisine to find cure for illness or imbalance?
For someone on this quest, it is worth exploring the Chinese cuisines , based on "YangSheng" life nourishment practices, Traditional Chinese Medicine framework and thousands of years of collective study and practice of medicinal foods.
One of the biggest value of Chinese dietary advice on for wellbeing and medicinal purposes is a different conceptual framework, with emphasis on achieving balance (Yin-Yang theory), eating seasonally and in accordance to ones constitutional makeup (5 Elemental Phases theory) and applying the Chinese Medicine theory of pathogens within human body that can be the root causes of various diseases and ailments (e.g hot-cold, damp-dry, excessive-deficient, stagnation, wind, heat, brittleness, etc).
Chinese medicinal culinary teachings are thousands of years old, based on observation and continuous improvement, making them uniquely time proven and effective, often providing solutions where Western medicine may be lacking.
One of the key values of "food medicine" is that they work on the principle of nourishment. Instead of taking pills to kill this and suppress that, this type of medicine uses foods based on individual and seasonal perspectives to achieve inner nourishment and balance.
As early as 1330 AD , the court physician Hu Sihui penned the "Principles of the Correct Diet", which included 200 herbal soups to bring the body into equilibrium, with the tradition of drinking medicinal soups still practiced today in China and prescribed by Traditional Chinese Medicine practitioners.
As a practical tip that is universally helpful to all humans and often not known in cultures outside of China and Asia is to drink hot water on regular basis and limiting/avoiding cold water. This very common sensical practice is yet to become popular as a form of therapeutic and wellbeing practice in the Western world. Cold water clashes with the organ of Stomach, making it harder to digest and metabolise food, gradually weakening the Stomach, digestion and thus the wellbeing. Try drinking warm water (not super hot) throughout the day and see how it effects you over a period of time.
If you are interested in this type of "food medicine" , you should consult with one or several Chinese Medicine practitioners to understand your constitutional makeup and possible imbalances. Once you know what your issues are, you can continue your research based on your personal needs.
