For thousands of years the Ancient Chinese recognised that certain Feng Shui Arrangements could disturb our healthy condition. In particular The School of Form and Shape alongside the Flying Stars Method gives a lot of information on how to remedy various health issues.
We know that in Feng Shui "Health Issues" are often caused by negative "unseen" energy combinations which gather either as a result of negative yearly influences or underlying energies that are triggered in a building via renovation, wrong furnishings, wrong feng shui colors. So, having positive "Health Remedies" around you, in your Bedroom, at your Work Place or carrying them on your person helps.
Health remedies can be added to the building when the Flying Stars has detected "health problems" in particular sectors. Or they can be added intuiitively around the home to stimulate 'Health Chi.' Or they can be carried on the Person to reduce negative energies.
