Kombucha is a fermented tea beverage that has gained traction for its health benefits and unique flavor. Born out of the fusion of ancient traditions and modern wellness trends,many people love drinking kombucha because it can help improve digestion, increase energy, and enhance immune function due to the probiotics and antioxidants present in the drink. Similar to craft beer, kombucha has its own artisan movement, with local brews popping up everywhere. It is a wonderful way to support local businesses; and it is fun and easy to brew your own!

Preserving: Before refrigeration, shrubs were used to preserve fruits and vegetables.
Preventing scurvy: The British navy used shrubs in the 18th century to combat scurvy.
Alcohol alternative: Shrubs were popular during Prohibition as an alternative to alcohol.
Cocktail ingredient: Shrubs are commonly used in cocktails, especially with rum or brandy.
In this class with Adam and Dianna, you'll learn about the history and you'll get to sample a variety of options for using shrubs in your kitchen. This was one of our most popular classes last year, so don't wait to sign up!

The renal system includes our kidneys, ureters, bladder and urethra. This system is known mostly for waste removal.

We will also discuss a few of the commonly used herbs that help support kidney health such as cleavers, nettle, dandelion, juniper berry, pipsissewa, and burdock. We will discuss a family of herbs known as alteratives, are used to gently enhance normal elimination via the major eliminatory organs (liver, kidneys, bowel, skin, lymph, and lungs). These organ systems are interrelated, and these herbs can often act on these interconnected eliminatory systems.
