I have a few of my favourites. But everyone is different. In general I would suggest to start on an adaptogenic herb, which can help you adapt to life stressors, physical, emotional, environmental and spiritual. This could be a certain medicinal mushroom, tonic leaf or root tea. My own favourites are gynostemma and reishi. If you know me personally you will always hear me talking about them!
I’d also add few others depending on what I’d be working on at the moment. This could be astragalus for my immunity, he shou wu for deep nourishment, dong quai to balance my hormones etc. If you have a question about how to get started I’d be happy to guide you through.
