Herbs that Drain Fire

Which of the following herbs clears heat, but also tonifies yin and moistens dryness, meaning it can be used for both excess and deficiency heat?

Zhi Mu clears excess heat, as in the formula Bai Hu Tang. It also clears deficiency heat, as in the formula Zhi Bai Di Huang Wan. Zhi Mu means "know your mother," so maybe that can help you remember that it clears deficiency heat and tonifies yin (KI yin xu heat is a common diagnosis for menopausal women).
