Using natural remedies for physical problems is perfectly fine, although one should be careful not to neglect traditional Western medicine in favor of alternative therapies. I strongly recommend consulting your regular personal physician for his advice and supervision of your overall medical care.
Using alternative medicines is fine, but one should be careful not to participate in non-Christian Eastern spirituality. It is participation in non-Christian Eastern spirituality that can be problematic, not medicinal therapies for physical ailments that were developed in the East.
