There are herbs to slow down the aging process if one is interested in them. Of course the best anti aging protocol is through consistent yoga and other similar spiritual practices and of course, healthy diet.
But Gynostemma pentaphyllum/ immortality herb and He shou Wu/ Fo-Ti help to preserve aging. I plan on using them for something myself because of accompanying benefits other than anti-aging.
There are other natural supplements for anti-aging out there if anyone is interested.
As I always say, its best to combine the spiritual with the physical.
