• Since the dispersing effect of some of the herbs in this category is dependent on their volatile oils, they are often decocted only for a short time (or are infused only) since heat causes volatization of these oils. Toasting them thus tends to moderate their effect.
• These herbs should be used with caution in cases of Yin deficiency.
• Herbs in this category are frequently combined with:
A. Herbs that clear heat when there is heat associated.
B. Herbs that warm the interior when there is cold associated.
C. Herbs that tonify the spleen when there is spleen Qi deficiency.
D. Herbs that promote Qi circulation, since moving Qi can help in the elimination of dampness.
