Gua Sha (Scraping Therapy)
Medicinal Profile of
Gua Sha (Scraping Therapy)
Gua Sha is a traditional East Asian healing technique that involves scraping the skin with a smooth-edged tool, usually made of jade, horn, or stone, to create light petechiae (“sha”). This practice stimulates circulation, releases muscular tension, clears stagnation, and helps the body expel heat or toxins through the surface. In terrain terms, it is most indicated for congestive, stagnant, and excitatory heat patterns, where blocked flow in the muscles, fascia, or circulation creates pain and irritation. Gua Sha is not pharmacological like most functional agents, but acts through terrain-level mechanisms, mobilizing fluids, releasing stagnation, and resetting nervous and muscular patterns.
-
👉Qualities describe the felt nature of a substance or practice, and how it acts in the body beyond nutrients or chemistry.
Circulating – Promotes blood and lymphatic flow, moving stagnation.
Releasing – Discharges pent-up tension and surface-level heat.
Stimulating – Activates tissue repair and metabolic activity locally.
Clearing – Helps eliminate toxins and inflammatory buildup from congested tissues.
-
Tool Selection – Traditionally jade, horn, or ceramic spoons; modern versions include stainless steel or specialized gua sha tools.
Medium – Oil is applied to reduce friction and protect the skin.
Application – Tool is scraped firmly but gently along the skin, usually following meridians or muscle lines, until redness or petechiae appear.
Frequency – Can be done acutely during stagnation, tension, or early illness, but should not be overused in depleted states.
-
Microcirculation Enhancement – Scraping increases capillary blood flow, improving oxygen and nutrient delivery to tissues.
Lymphatic Drainage – Stimulates lymph movement, clearing metabolic waste and excess fluids.
Neurovascular Modulation – Activates sensory nerves, resetting pain perception and reducing hypersensitivity.
Inflammation Modulation – Triggers a mild controlled inflammatory response that upregulates anti-inflammatory mediators.
Surface Venting – Promotes release of heat and stagnation through controlled petechiae.
Indicated Patterns by Affinity
👉 Indicated patterns describe the functional state of the body and its organs and/or tissues, showing whether they are dry, atrophied, too damp (pressure), stagnant, lax, inflammed, sluggish, tense or underactive. The Primary Indicated Pattern is the main state where this remedy works best. Secondary Indicated Pattern(s) are the patterns that often develop over time when the primary state is left unaddressed. The primary pattern must be supported first, as this allows the secondary patterns to naturally ease or resolve.
👉Affinities are the organ systems and tissues where the remedy acts most strongly.
-
Tension / Spasmodic Holding (Primary Indicated Pattern) – Muscles and fascia are locked, tight, or resistant to movement.
Examples: stiff neck, shoulder knots, back spasms.Gua Sha’s scraping strokes mechanically release fascial adhesions and relax spasms, restoring circulation and mobility.
Congestive Pressure (Secondary Indicated Pattern) – Stagnant blood and fluids build up in muscle tissue, creating heaviness and discomfort.
Examples: deep muscle soreness, post-exercise congestion, chronic stiffness.The scraping action stimulates microcirculation and clears stagnant blood, relieving heaviness.
-
Congestive Pressure (Primary Indicated Pattern) – Sluggish blood or lymph flow contributes to swelling or stagnation.
Examples: edema, puffiness, poor circulation in limbs.Gua Sha enhances lymphatic drainage and blood perfusion, moving stagnation out of tissues.
Excitation / Irritation (Secondary Indicated Pattern) – Localized vascular reactivity and inflammatory congestion. Examples: tissue heat, swelling, red irritated areas.
By venting surface heat and mobilizing circulation, Gua Sha reduces inflammatory load.
-
Congestive Heat (Primary Indicated Pattern) – Pathogens or fluids obstruct the chest, lungs, or bronchi, producing heat and congestion.
Examples: chest colds, wet cough, asthma with phlegm.Scraping the upper back and chest improves lung surface circulation and helps release phlegm and pathogens.
Tension (Secondary Indicated Pattern) – Restricted breathing from tight intercostal or chest wall muscles.
Examples: shallow breathing, stress-tightened chest, post-cold stiffness.Gua Sha relieves muscular restriction around the rib cage, allowing freer respiration.
-
Tension (Primary Indicated Pattern) – Stress accumulates in muscle holding patterns, leading to physical and mental tightness. Examples: jaw clenching, shoulder tension, tension headaches.
Gua Sha discharges held tension and relaxes the nervous system via sensory stimulation.
Excitation (Secondary Indicated Pattern) – Nervous overstimulation contributing to irritability, restlessness, or pain sensitivity. Examples: stress-related insomnia, pain flare-ups, agitation.
The scraping process shifts nervous input, promoting calm and resetting pain pathways.
-
Excitation / Irritation (Primary Indicated Pattern) – Surface-level heat, redness, or inflammation venting through the skin. Examples: early-stage cold/flu, red patches, surface stagnation.
Gua Sha creates controlled petechiae that vent heat and release congestion from the skin.
Congestive Pressure (Secondary Indicated Pattern) – Stagnation showing at the skin surface. Examples: dull skin tone, sluggish healing, superficial swelling.
Improved circulation nourishes tissues and clears stagnation at the skin level.

👉 Medicinal actions describe the specific ways a food influences organ systems and body functions.
(Note: These are not pharmacological actions, but terrain-level influences through mechanical stimulation and circulation.)
Musculoskeletal System
Myorelaxant – Releases tight or spasmodic muscles by breaking fascial adhesions.
Analgesic (Indirect) – Relieves pain by increasing blood flow and reducing stagnation.
Circulatory & Lymphatic Systems
Circulatory Stimulant – Increases microcirculation and tissue perfusion.
Detoxifying Agent – Enhances lymphatic drainage and removal of metabolic waste.
Respiratory System
Decongestant (Traditional Use) – Opens chest circulation and clears mucus congestion when used on the upper back and chest.
Nervous System
Stress Releaser – Relieves nervous tension by discharging held stress through muscle release.
Regulator – Resets pain response patterns by stimulating skin and nerve endings.
Integumentary System
Surface Venting – Creates controlled microtrauma to vent heat and promote detoxification through the skin.
-
3rd Degree – Gua Sha exerts a powerful influence on the body, producing immediate and visible changes in circulation, pain relief, and tissue release. While highly effective, its strong stimulation requires skill and care to avoid overuse.
-
Herbal Allies – Circulating herbs like ginger, cayenne, or cinnamon for internal support.
Functional Agents – Sauna, steam, or hot packs to enhance circulation and detox.
Foods – Warm, light meals post-treatment to support circulation without burdening digestion.
-
Avoid in people with bleeding disorders, on anticoagulants, or with fragile skin.
Do not apply over open wounds, active infection, or inflamed rashes.
Should be avoided in states of extreme depletion or collapse.
Petechiae are normal and should not be mistaken for bruising, but care is required to avoid excess force.
