Which herb enters the Kidney channel?

• A. Deng Xin Cao
• B. Gan Jiang
• C. Tian Men Dong
• D. Ban Xia

Answer: (C)

The herb that enters the Kidney channel is Tian Men Dong. It’s a classic Yin-nourishing herb whose actions and traditional use align with the Kidney channel, supporting Kidney Yin deficiency and related symptoms such as dryness, night sweats, and throat discomfort. Tian Men Dong not only nourishes Kidney Yin but also has affinities that cover the Lung Yin as well, which is why it’s repeatedly described in texts as moving through the Kidney (and, to a lesser extent, the Lung) channels. The other herbs listed are used with primary effects on other channels, not the Kidney, so Tian Men Dong best fits the channel-entry criterion.
