Herbal Action: Diaphoretic

Nov 1, 2025
1 min read

Also called sudorifics - increase perspiration


Diaphoretic herbs increase perspiration and influence the entire circulatory system. They promote increased perspiration and dilate capillaries, increasing elimination through the skin — helping the body eliminate viruses and break a fever.


Diaphoretics fall into three classes, matched to the person's state:

  1. Stimulating — for when the overall state is sluggish or unresponsive

  2. Neutral — safe for general use

  3. Sedative — for acute distress, or when there is hypertension


What they do:

  • Increase perspiration

  • Dilate capillaries, increasing elimination through the skin

  • Help eliminate viruses

  • Break a fever


How they're used:

Diaphoretic herbs are best consumed as a hot tea, since the warmth itself supports the sweating response the herbs are working to encourage.


When to consider them:

Fevers, colds, flu, edema (swelling caused by excess fluid in body tissues) and skin conditions.
