What it is

Nielsen defines gua sha as instrument-assisted, unidirectional press-stroking of a lubricated body surface. It deliberately raises "transitory therapeutic petechiae", meaning small amounts of blood leave the vessels into the tissue under the skin. Other names for it include coining, spooning and…

Format

• Physiology studies, such as microcirculation measured in small groups of healthy volunteers, describe what happens in the tissue. They do not show clinical benefit.
• 2e. The psychotherapist's work: stages (no fixed session count)

Who practises it, and how they are trained or regulated

• 2b. Who delivers it and how they are regulated
• In clinics, gua sha is mainly practised by acupuncturists and other practitioners of East Asian medicine. Some US states name it in the acupuncture scope of practice. For example, New Jersey's rules list "gua sha scraping techniques" and cupping among the methods licensed acupuncturists may use (N.J. Admin. Code 13:35-9.12). A 2003 Maine bill also listed gua sha among the techniques of oriental medicine.
• Nielsen's training is a certificate course for practitioners. Her stated rule is to use these techniques only if "trained by a qualified instructor".

Evidence status, as the guide reports it

• There is no psychotherapy protocol here. The framework below covers four things: the practice as described, who delivers it, safety and evidence, and the stages the psychotherapist's own work moves through.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• your own pull to help directly, and dual-role confusion. It is working when the boundary is held and the client still feels cared for.
• the client blaming themselves, and delay in getting medical care. It is working when medical care is reached and the client knows how to make a complaint.
• the client feeling criticised, and reliance on coining for symptoms that need medical care. It is working when the client can name the situations in which they would see a doctor.
• pressure on you to accept the explanation and skip referral, and a baby who is unwell. It is working when the referral is made promptly and documented, and the parents have been told.
• strong emotional reactions to the marks, a pattern of needing scraping to cope with distress (The Conversation describes perceived dependence), and use as a form of self-injury. If self-injury is…

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
