Something can simultaneously be a pseudo-science and still work. Do some aspects of TCM have benefits? Sure, probably – it's a huge field. But that's more coincidental than anything else, and their mechanisms of action are unrelated to TCM's pseudo-scientific theories. If you go to a forest and start eating random stuff then some will also have some benefit.

I'm not familiar with the history of meditation or mindfulness, but I've seen people claim some pretty ridiculous things about yoga, perhaps the most ludicrous was someone claiming that some positions will prevent certain cancers due to "massaging your organs". Yoga absolutely has benefits but that's just nonsense.
