This art of tonic herbalism is aspirational, not necessarily just solving the problems we're seeing in our body, so we like to often make our tonics from a place of "how bloody good can it get in my body?!" And mix it up from there (I just did a big ranting 11 min podcast on mixing herbs if you want to jump to that).
That's where you'll feel any worries about "can I mix this herb with this one ", or "can I put 2 blends together?!?! Ahhhh!!!" wash away and that mad scientist of longevity comes out to play and cultivate.
When I'm in this space I'll often make what I call the Million Dollar Tonic - using the 3 Treasures Bundle. It's a heaped tap of each of the JING, QI, and SHEN blends. Normally in a tea. Blend. Annihilate. Have an EPIC day cultivating virtue and wins.
Practitioners and clinical herbalists and the institutionally-bound have a tendency to create fear around working with herbs independently. I've had many debates with newly graduated TCM students who project their, warranted, protective energy over the sick, with symptoms that shouldn't have random herbs thrown at them, at me, because these doctors and institutional healers approach herbalism from a "lowest common denominator" approach. "There are people who are sick and they'll harm themselves with those drying / tonifying etc herbs! so no one should be able to get them! Even people who are slightly deficient or well who will have astronomical benefits from taking them for years! And who will learn a lot about there body in the meanwhile! rendering me useless to them!!!"
Ok I might have added the last part hahahaha. But exaggeration helps me highlight a reality of the herbal world we're in. I think you get my point. Mix your herbs, experiment, get the feedback from your body, don't be scared, have a practitioner monitor you if you're nervous until you see that you're getting away from being a patient and into being a cultivating badass.
