Somewhat True, but "don't throw the baby out with the bathwater".
Much of "traditional medicine" is empirically based. The models they came up with to explain the mechanisms may not be valid in light of today's Scientific Knowledge but they are instructive nevertheless (rungs in a ladder leading to better understanding etc.) As an example we still don't know how exactly Acupuncture works but do know that it works for many cases.
Right, but we don't have any reason to assume it to be true if there's noe evidence to support it - which would be step one in determining whether its a reasonable belief, and integrating it into modern medicine.
As for your example, we do not know that acupuncture works - conclusions are inconsistent in systematic reviews, which would suggest that it's not effective. Most researchers I've heard speak about the subject seem to believe any perceived reduction in pain to be due to placebo.
