The Damp-Removing Specialists – Qiang Huo, Cang Zhu, Fu Ling (Materia Medica Edition)

Part 2: External Invaders – The Six Climatic Influences (六氣) and Defensive Strategies
Sub-Part 2.3: Sticky Dampness – Damp Pathogenic Influence (濕邪)
Lecture 15: The Damp-Removing Specialists – Qiang Huo, Cang Zhu, Fu Ling

In the previous lecture, we examined the heavy, sluggish symptoms that appear when dampness enters the body, and we distinguished between internal and external dampness.

Because dampness is sticky and lingering—clinging tightly and resisting removal—we need the help of specialized “damp-removing experts” (materia medica) that act according to body region.

In Korean herbal medicine, herbs are strictly differentiated based on where dampness is lodged in the body—Upper (Shang Jiao), Middle (Zhong Jiao), or Lower (Xia Jiao).

1. Removing Dampness from the Upper Body (Upper Jiao): Qiang Huo & Cang Zhu

When the shoulders and back feel heavy and stiff, or when the entire body aches more on rainy days, dampness is often lodged in the Upper Jiao (上焦).

• Qiang Huo (羌活)

Qiang Huo has a powerful dispersing nature.
It acts particularly along the Taiyang Bladder channel, targeting the back and shoulders. It is especially effective for expelling dampness from the posterior body and alleviating generalized body pain.

• Cang Zhu (蒼朮)

Cang Zhu is a representative herb for drying dampness.
It dries damp accumulation in the Spleen and Stomach and is often combined with Qiang Huo when dampness in the Upper Jiao causes heaviness or difficulty sweating.

---

2. Removing Dampness from the Middle (Middle Jiao): Fu Ling & Ze Xie

Abdominal fullness, diarrhea, or swelling occur when water metabolism in the Middle Jiao (中焦) is impaired.

• Fu Ling (茯苓)

Fu Ling is a core herb for promoting urination and draining dampness.
It guides excess fluid downward and out through urination. At the same time, it calms the mind while clearing unnecessary internal moisture.

• Ze Xie (澤瀉)

Often paired with Fu Ling, Ze Xie helps eliminate dampness from the Middle Jiao.
It is particularly effective when urination is scant or difficult.

3. Removing Dampness from the Lower Body (Lower Jiao): Sheng Ma & Fang Feng

Swelling and pain in the lower back and legs, or weakness in the lower limbs, signal damp accumulation in the Lower Jiao (下焦).

• Sheng Ma (升麻)

Sheng Ma lifts sunken qi upward and helps disperse dampness that has settled below.

• Fang Feng (防風)

Literally meaning “Guard Against Wind,” Fang Feng expels wind-damp from the channels.
It disperses dampness lodged in the meridians and is used for generalized pain and Taiyang channel disorders.

Upper Jiao (Upper Body)	Shoulder/back pain, heavy body aches	Qiang Huo, Cang Zhu

Treating dampness is like drying wet laundry and draining stagnant water.

External dampness must be dried with dispersing herbs like Qiang Huo and Cang Zhu.
Internal dampness must be drained downward and eliminated with herbs like Fu Ling and Ze Xie.

Only then can the body regain lightness.
