It's not difficult to find traditional eastern wisdom that have no known health benefits and can have adverse effects. Just look at Gua Sha for example. Not everything is good in TCM, a lot of it is not well tested following theories that are demonstrably false.
Does it mean that there's nothing of interest? No. There are some remedies based on Traditional Chinese Medecine that have proven to be beneficial. After all, this is how Artemisinin which is used as a cure for Malaria was discovered from a traditional herbal remedy from the 4th century. But, this is after trying multiple traditional remedies. Don't underestimate the value of curation when finding a working remedy from the multitude of non-working traditional cures.
