Yarrow and Passion vine are happy together and work well for balancing the body.
Passion vine is a very effective nervine- helping to calm the system and stop racing/looping thoughts. But, it doesn't provide much for the rest of the body. Yarrow is a great compliment to those properties. Yarrow is a grounding herb, adding balance to the body, improving the circulatory system and improving tissue repair.
