Every year, during the summer on certain days, there is a tradition of applying a paste of warming herbs to points on the back to support immunity in the coming winter. We call this San Fu Moxa. After burning regular Moxa on freshly cut ginger slices (shown in this video), we grind warming San Fu spices and apply them as a paste to points on the back associated with the lungs. The herbs are stuck to the back with skin-friendly tape and remain there for about 4 hours to do their job. It is a traditional treatment for the prevention of allergic rhinitis, bronchitis and asthma. This tradition has never been more important than it is now!
