Gua Sha tools Buying Guide

I. Equipment Introduction

1. Equipment Overview Gua Sha tools, as indispensable instruments in traditional Chinese medicine Gua Sha therapy, are essentially devices used to scrape specific areas of the human body surface to achieve therapeutic and health-preserving purposes such as promoting blood circulation and dispelling stasis, clearing meridians, detoxifying and releasing the exterior, and harmonizing Qi and blood. Through mechanical stimulation of the skin and subcutaneous tissues, they promote local capillary dilation, forming "sha marks," thereby improving microcirculation, accelerating the excretion of metabolic waste from the body, and alleviating various discomfort symptoms caused by Qi and blood stagnation and blocked meridians. Gua Sha tools are key carriers for realizing the core function of this ancient therapy.

2. Introduction to Equipment Types Gua Sha tools come in various types, mainly classified by their material and shape:

   • Classified by Material:
     • Bian Stone Gua Sha Board: Made from natural Sibin Bian stone and other materials, it has a warm and smooth texture, is rich in various trace elements beneficial to the human body, possesses properties of warming Yang, calming the mind, and promoting blood circulation, and is considered a superior choice for Gua Sha.
     • Jade Gua Sha Board: Such as Xiuyan jade, jadeite, etc., it has a fine and smooth texture, a cool touch, and functions to clear heat and calm, often used for facial Gua Sha or areas requiring heat-clearing.
     • Horn Gua Sha Board: Made from natural buffalo horn, ox horn, etc., it has a tough texture, is not easy to damage the skin, is rich in keratin, has low irritation to the skin, is not prone to static electricity, and is a commonly used material in clinical and home settings.
     • Ceramic/Resin/Plastic Gua Sha Board: Modern industrial products, lower cost, easy to clean and disinfect, diverse in shape, but their energy conduction and health benefits are relatively weaker than natural materials.
     • Metal Gua Sha Board: Such as stainless steel, sturdy and durable, easy to clean, but has strong thermal conductivity, requiring attention to temperature control during its use.
   • Classified by Shape: Common shapes include fish-shaped, comb-shaped, S-shaped, wave-shaped, plate-shaped, acupoint pen-shaped, etc. Different shapes are designed to better fit the curves of various parts of the human body or to achieve different techniques such as pressing and scraping.

3. Introduction to Equipment Functions The core functions of Gua Sha tools lie in their physical stimulating effect and the auxiliary effect of their materials:

   • Physical Stimulation Function: Through friction and pressure with the skin, Gua Sha tools produce mechanical stimulation on local tissues, promoting capillary dilation, increasing local blood flow, and improving microcirculation. This stimulation helps activate immune cells, promote inflammation absorption, and tissue repair.
   • Promoting Blood Circulation and Dispelling Stasis Function: The "sha marks" produced by scraping are caused by subcutaneous capillary rupture and bleeding. This is a type of "blood outside the vessels" that can stimulate the body to produce a stress response, accelerate blood circulation, clear pathological products, and achieve the effects of promoting blood circulation, dispelling stasis, reducing swelling, and relieving pain.
   • Clearing Meridians Function: Gua Sha tools can be used to scrape along the direction of meridian pathways or at specific acupoints, stimulating meridian acupoints, regulating Zang-Fu organ functions, balancing Yin and Yang, thereby achieving the purpose of treating and preventing diseases.
   • Material Property Function: Gua Sha tools made of different materials possess their unique physical and chemical properties. For example, Bian stone has far-infrared and ultrasonic properties, which can deeply warm tissues; the coolness of jade helps clear heat; and the gentle properties of horn are more suitable for sensitive skin. These characteristics can further enhance the therapeutic and health-preserving effects of Gua Sha.

II. Scope of Application

1. Application Scenarios Gua Sha tools have a wide range of application scenarios, usable in both professional medical institutions and for daily health care:

   • Sub-health Conditions: Chronic fatigue syndrome, low immunity, body aches, limb numbness, etc. It helps improve physical constitution.
   • Beauty and Health Care: Facial Gua Sha can promote blood circulation, improve skin tone, and reduce fine lines.

3. Contraindicated Groups To ensure the safety and effectiveness of Gua Sha therapy, the following groups or conditions should avoid Gua Sha or use it cautiously under the guidance of a professional:

   • Individuals with skin damage, infection, ulcers, inflammation, or allergies: To avoid aggravating infection or irritation.
   • Individuals with bleeding tendencies: Such as hemophilia, leukemia, thrombocytopenia, or those taking anticoagulant medications, as Gua Sha may lead to uncontrollable bleeding.
   • Pregnant women's abdomen, lumbosacral region, and nipple areas: May induce uterine contractions or affect the fetus.
   • Patients with malignant tumors and those with unexplained local lumps: To avoid stimulating tumor spread.
   • Patients with severe cardiovascular and cerebrovascular diseases, liver and kidney dysfunction, or edema: May worsen the condition or cause discomfort.
   • Individuals who are extremely weak, frail elderly, have highly sensitive skin, or severe skin diseases: Poor skin tolerance, easily damaged.
   • Individuals in the early stages of bone fracture or with recent local trauma: To avoid aggravating the injury.
   • Individuals on an empty stomach, overly full, after drinking alcohol, or excessively fatigued: At this time, the body is not in good condition, and Gua Sha may cause collapse or discomfort.
   • Individuals with severe local circulatory disorders such as varicose veins or lymphedema.

III. Usage Guidelines and Precautions

1. Usage or Operation Method/Steps

   • Preparation:
     • Clean the skin of the Gua Sha area, ensuring no damage or infection.
     • Apply an appropriate amount of Gua Sha oil, petroleum jelly, vegetable oil, or professional Gua Sha medium evenly to the Gua Sha area to reduce friction and protect the skin.
     • Select a suitable Gua Sha tool and ensure it is clean.
   • Holding Posture: The Gua Sha tool is usually held at a 30-60 degree angle to the skin. The edge of the Gua Sha board should be smooth and rounded, avoiding direct contact of sharp angles with the skin.
   • Scraping Technique:
     • Direction: Generally from top to bottom, from inside to outside, scraping in one direction only, not back and forth. It should follow the direction of meridian pathways or muscle fibers.
     • Strength: The force should be even and moderate, to the extent the patient can tolerate, ideally feeling slight soreness and distension, and skin redness. Do not use violent scraping.
     • Area: Select the Gua Sha area according to the condition, such as the back, neck and shoulders, limbs, etc.
     • Sha Appearance: Stop scraping when red or purplish-red spots (sha marks) appear on the local skin. There is no need to force more "sha" to appear.
   • Post-Gua Sha Treatment:
     • Wipe the Gua Sha area with a warm, damp towel to remove excess medium.
     • Advise the patient to drink warm water to promote metabolism.
     • After Gua Sha, pay attention to keeping warm, avoid exposure to wind and cold. The Gua Sha area should not be bathed (especially with cold water) before the sha marks have faded.

2. Common Mistakes Reminder

   • Improper Strength: Excessive Gua Sha strength can easily damage the skin, cause pain, and even subcutaneous tissue contusion; too little strength will result in poor efficacy, failing to achieve the purpose of promoting blood circulation and dispelling stasis. It should be adjusted according to individual tolerance and condition.
   • Incorrect Gua Sha Direction or Repeated Scraping: Incorrect Gua Sha direction may hinder the circulation of Qi and blood, while scraping back and forth can easily damage capillaries and aggravate skin irritation. Always scrape in one direction, following the meridians or muscle fibers.
   • Insufficient or Unused Gua Sha Medium: Scraping dry skin increases friction, leading to skin damage, pain, and even infection. Always use sufficient lubricating medium.
   • Ignoring Contraindications: Performing Gua Sha on individuals or areas with contraindications may trigger severe adverse reactions, such as bleeding, infection, or worsening of existing conditions. Before use, a detailed medical history must be taken and skin condition checked.
   • Excessive Gua Sha Frequency or Improper Area Selection: The same area should not be scraped too frequently. Generally, the next session should only be performed after the sha marks have completely faded (usually 3-7 days). Gua Sha areas should be selected according to TCM theory or professional guidance, avoiding blind scraping.
   • Failure to Keep Warm After Gua Sha: After Gua Sha, pores open and superficial circulation accelerates. If exposed to wind and cold at this time, it can easily lead to colds or other discomforts.
   • Incomplete Cleaning and Disinfection of Gua Sha Tools: Especially when multiple people share tools, inadequate cleaning and disinfection can lead to cross-infection. Thorough cleaning and disinfection are required before and after each use.
   • Over-pursuit of "Sha" Appearance: The amount and color depth of sha marks are related to various factors such as the condition, constitution, and technique, and more sha is not necessarily better. Excessive pursuit of sha may lead to skin damage and physical weakness.
