Smoking herbs

I haven’t found smoking to be a suggested way to ingest mixture of herbs in my learning or TCM but I’ve only studied for the last 5 years or so.

I’ve read that they often experimented with smoking the herbs/mixtures but often preferred other methods.

Besides some (in Yellow Emperor iirc) stories of casual use of potent remedies that included the candid use of mercury by the wealthy, I don’t recall reading much more about smoking being prescribed.
