Because the physical quality of different age groups is different, and it should be treated according to everyone's specific situation. The objective way is to ask your grandfather to do a comprehensive examination to see how his body is in all aspects, or to see Chinese medicine to see if Chinese medicine has any relevant suggestions. Because compared with western medicine, Chinese medicine may pay more attention to some health preservation methods. And everyone's absorption degree is different, so the effect is different.

It is more scientific and reasonable to consult a doctor. Finally, I wish your grandfather find a suitable health care method as soon as possible, good health and all the best.
