As the demand for trauma-informed, body-based mental health care continues to rise, clinicians and clients alike are seeking therapies that move beyond talk therapy alone.
One powerful and often underutilized adjunct to Body Psychotherapy (Somatic Therapy) is the 5 Needle Point protocol (5NP) — also known as Acudetox, Acuwellness, auricular acupuncture, and 5-point ear acupuncture.
When integrated thoughtfully, Acudetox can enhance nervous system regulation, deepen nonverbal processing, and expand access to trauma and addiction recovery support.
What is Body Psychotherapy?
Body Psychotherapy — also known as Somatic Psychotherapy — is a therapeutic modality grounded in the understanding that the mind and body are inseparable.
Body Psychotherapy works with emotional, cognitive, relational, and physiological processes simultaneously. Rather than focusing solely on thoughts, somatic therapy supports clients in tracking sensation, regulating the nervous system, resolving stored trauma, increasing embodied awareness, and integrating nonverbal experience.
What is Acudetox/5 Needle Protocol (5NP)?
The 5 Needle Point protocol (5NP) — also known as Acudetox, Acuwellness, auricular acupuncture, and 5-point ear acupuncture — “is one of the most commonly used forms of acupuncture treatment in the United States” (Carter et al., 2017).
“The term ‘Acudetox’ was adopted to differentiate it from other forms of acupuncture, indicating that this is a standardized protocol, not requiring the practitioner to make a diagnosis and determine treatment points” (Stuyt & Voyles, 2017).
5NP entails inserting disposable, sterile acupuncture needles into five specific points of each ear subcutaneously, where participants sit quietly for 30–45 minutes (NADA, 2023).
The predetermined ear points are: Sympathetic, Shen Men, Kidney, Liver, and Lung. These points have demonstrated effects on emotional, cognitive, endocrine, neuropsychologic, and biochemical levels (Carter et al., 2014).
The liver corresponds with anger, the lungs with sadness, and the kidney with fear. The Shen Men point reduces anxiety, while the sympathetic point calms excess sympathetic activation and supports parasympathetic regulation (Buchanan et al., 2018).
A nonverbal approach to trauma healing
Apart from other mind-body therapies, 5NP is “more passive in that participation can be entirely non-verbal” (Carter et al., 2017).
Those too traumatized to talk about their trauma have significantly benefitted from the nonverbal and passive experience of 5NP (Stuyt & Voyles, 2016; Landgren et al., 2019).
In the documentary “Unimagined Bridges” (Cooley, 2008), data collected after September 11, 2001 revealed that among 40,000 mental health visits over six years, only 0.1% chose talk therapy, while 55% chose acupuncture and 44% chose massage or energy work.
By incorporating nonverbal communication, we engage with the entirety of the organism.
5NP as a somatic tool for nervous system regulation
5NP is labeled as a somatic tool that may be more effective than other mindfulness-based therapies due to its immediate effect on physiological and psychological distress (Carter & Olshan-Perlmutter, 2015).
Research suggests that 5NP creates immediate calming effects, reduces sympathetic overactivation, supports parasympathetic regulation, and enhances stillness and presence.
Stuyt (2014) notes that 5NP can help clients become more mindful and present, creating an opening for deeper therapeutic interventions and enhancing engagement in treatment.
Applications of Acudetox/5NP
5NP has been applied in substance abuse recovery and detox programs, harm reduction models, long-term recovery treatment, criminal justice settings, behavioral health programs, chronic pain management, and disaster response initiatives.
It has supported disaster response and emotional trauma healing, fostering dignity, hope, and resiliency (Voyles et al., 2020).
5NP has served adults, parents, teenagers, LatinX communities, LGBTQ+ individuals, unhoused populations, seniors in low-income housing, families in community programs, individuals in drug courts, People of Color within the justice system, and individuals navigating trauma and mental health challenges.
How 5NP/Acudetox enhances somatic psychotherapy
The insertion of the needles enables individuals to bypass the immediate necessity for verbal expression and initiate exploration of present-moment experience through intensified nonverbal cues and felt sense.
Clinically, the needles act as guides — enhancing sensory awareness, emotional tolerance, nervous system balance, nonverbal processing, fostering self-acceptance, and creating a more direct connection with sensations and emotions within the body.
Rather than replacing psychotherapy, 5NP can create the physiological conditions that make somatic therapy more accessible and effective.

FAQ’s for Acudetox Therapy
What is acudetox therapy (the 5-needle protocol)?
Acudetox therapy is a standardized ear-acupuncture protocol that uses five specific points on each ear. Clients typically sit quietly for about 30–45 minutes, making it a simple, structured adjunct to care.
Is acudetox therapy the same as the NADA ear acupuncture protocol?
Yes. “Acudetox,” “5 needle protocol (5NP),” and “NADA protocol” are commonly used to describe the same standardized 5-point auricular (ear) acupuncture approach.
How does acudetox therapy support nervous system regulation?
It’s used as a somatic tool to help calm sympathetic overactivation and support a shift toward parasympathetic regulation, which can create more stillness, presence, and emotional tolerance.
Why is acudetox considered a nonverbal approach to trauma support?
Because participation can be entirely nonverbal. Clients don’t have to explain or recount trauma to receive support, which can be especially helpful when words feel inaccessible or overwhelming.
What are the five ear points used in the 5-needle protocol and what are they associated with?
The protocol uses Sympathetic, Shen Men, Kidney, Liver, and Lung points. In the blog’s framing: Shen Men is linked with easing anxiety, the Sympathetic point supports calming excess activation, and the other points are associated with emotional themes like fear, sadness, and anger.
What does an acudetox session feel like and how long does it take?
After the needles are placed, most people sit quietly. The experience is designed to be low-demand and inward-focused, typically lasting 30–45 minutes.
How does acudetox therapy enhance somatic psychotherapy without replacing it?
Acudetox can help create the physiological conditions (calm, presence, tolerance) that make somatic psychotherapy more accessible—so the therapy work can go deeper without forcing verbal processing.
Acudetox Therapy Can Support Trauma Healing
Trauma can feel like your body is working against you—but many of these reactions are your nervous system trying to protect you. Acudetox therapy (the 5-needle ear protocol) offers a quiet, largely nonverbal way to support regulation and stillness, which can make somatic psychotherapy more accessible—especially when talking feels like too much.
