Can I make kombucha from herbal tea?

Have you ever wondered if you can brew kombucha using a herbal infusion instead of traditional tea?

Maybe you are doing something like a “locavore challenge” and only eating and drinking what can be grown or produced within 100 miles of your home. Maybe you are a prepper of some sort, wanting to know if your kombucha scoby will survive on your local tea substitute plants. Or maybe you like the idea of bitter-herb spring tonics, but find them to be too, well frankly, bitter!

This question about using herbal tea to make kombucha is one of those queries that you’ll see come up time and time again in fermenting forums. It’s a variation of the “do I have to use normal tea?” question, and is usually answered with the traditional wisdom that ordinary black, green or oolong etc tea is what kombucha needs and that to stray from that is to invite disaster.

It appears that, like much of life, the truth is much less straightforward.

What I haven’t looked into on this website yet are any papers about the antioxidant activities of different types of tea.

Is Kombucha Healthy? A general introduction.

Simply Kombucha

The following article is adapted from the ‘Health Claims’ chapter in my book Simply Kombucha.

 

Kombucha has a long history of being promoted as a health drink. Almost every blog or article I read about kombucha has a list of medical complaints or illnesses that it is supposed to heal or at least help with.

All the early kombucha books from the 1990s are full of hints and tips about using kombucha to heal wounds, beat arthritis, or combat hair-loss. Even AIDS was claimed to respond to this amazing “miracle mushroom”.
On closer reading I found that the authors of those books also tended to speculate about cosmic rays and crop circles, making me a touch skeptical about their medical opinions, no matter how expert they were in the art of brewing kombucha. So I looked online to see what the current state of opinion was about kombucha’s healing powers.

Effect of kombucha on rats with drug-induced type 1 diabetes.

diabetic ratsWrapping my head around the ins and outs of this week’s paper has taken me a bit more time than usual. There is a lot going on here, but come along with me and we’ll go on a journey of discovery together.

This is a paper where the initial results look awesome, but on closer inspection need to be treated with care.
