Details of Diffuse Pain Decoction

Migrating aches aggravated by damp weather?

Cinnamon twig is a great blood mover which treats pain.

The Diffuse Pain Decoction was originally conceived of addressing the painful influences of exposure to wind or damp weather. Back in the 1170s, that was a pretty good idea, well before we enjoyed so much control over our environment.

Even with central heating and air conditioning autoimmune disregulation or changes in barometric pressure can still give rise to these aches and pains.

Pains that migrate are due to “wind”. One day it’s right here, then the next day it has moved over to the other side. That’s said to be wind clogging up the channels.

Dampness from the environment is as easy to recognize as the well-known arthritic pains that are arise with rainy weather. Dampness makes the limbs feel heavy and numb too. If the dampness goes a little more deep, it can generate dizziness or the sensation of a heavy head.

This formula is one of those “root & branch” treatments too. The branch means the symptoms that are due to the invasion of wind or damp as described above. Treating the root means strengthening the qi and blood since they prevent wind or damp from getting into the body.

Qi is the energy that can prevent the dampness from entering the body, so we stimulate the qi of the lungs as it is this qi that regulates the opening and closing of the skin pores. We use Huang Qi (Rx. Astragalus) to promote this lung qi. To address the wind, we recall an ancient treatment principle that suggests one treat the blood to expel the wind. This is done with the herb Dang Gui (Rx. Angelica Sinensis) and Bai Shao (Rx. Peony Alba).

This formula is best used to promote joint health when there are no visible deformities to the bones or tendons. If there are, consider Angelica Pubescens and Sang-Ji-Sheng Decoction instead.
