What is Lymphatic Enhancement Technology – LET

The brand name of Lymphstar Enhancement Technology, (LET)™ was created in 2006 by Arcturus Star Products and is a registered brand of the Company. The term represents a comprehensive technological innovation in wellness and rehabilitation therapy. The company began development of products utilizing vibrational energy technology in the early 1990s. They have pioneered this breakthrough technology from the complimentary and holistic professions to physical therapy and rehabilitation and, now, into lymphedema clinics in hospitals and private practice as well is in integrative medical, pain and plastic surgery practices. LET therapy is offered across the US, Canada and worldwide.

Lymphstar Enhancement Technology- LET™, represents the proprietary products, training seminars, and related research and academic studies of Arcturus Star Co. These are the proprietary achievements of Arcturus Star Company exclusively. The branding that represents it and are not to be adopted by other purveyors of ‘lymphatic drainage’ devices and/or hands-on therapies for skin and body. (massage techniques)

What is LET?

LET is a system of electronic instrumentation that aids in improving microcirculation, general circulation, helps with fluid management at the tissue level. It supports or can replace manual lymphatic methods.
LET Units offer several layers of electromagnetic energies that can assist with the release of interstitial toxins thus, helping with pain and acceleration of local healing. Also, a deeper view of the lymphatic system considers that the components of this body system also comprise the immune system. Thus, LET may assist the immune functions.

People are taught the care of the cardiovascular system, but generally, not the lymphatic system or the immune system overall. LET fills a gap in the integrative communities for substantial treatments that assist with detoxification at a deep cellular level and work locally and within and to aid the immune functions.

Massage professionals and estheticians are drawn to LET because they are taught methods of manual lymph drainage, such as the Vodder method.

Occupational and Physical therapists help sufferers of post cancer edema, post surgeries and injuries and find LET an exceptional addition to their practices.

LET may be used with or without hands-on techniques. Manual techniques are applied as needed for palpation of tissue to assess congestion, increasing flow, and enhancing fluid release if these techniques fall within the therapist’s scope of practice. Physical therapists, occupational therapists, massage therapists and registered nurses may apply manual therapies in conjunction with the application of LET instruments. Certified, trained lymphatic therapists may also apply some palpation and light skin – touch release techniques in conjunction with LET Instruments.


The LET Instruments from Arcturus Star Incorporate a Mild Electrostatic Energy Field (EEF) with Low Frequencies that are Dynamically – Pulsed with our Proprietary Method.
EEF is electro-static field that pulsates at microamperes (millionths of an ampere) at less than 1,000 Hz. The EF Field is generated through medical grade glass applicators with the enclosed noble gases being excited by high voltage at the source and converted to DC (direct current). (Argon, Xenon, Krypton)
Creates physical vibrations with acoustic pressure waves at variable low frequencies.
The oscillations are modulated by a proprietary design call Sweep Pulse/ Dynamic Wave Pulse (SP/DWP.)
This wave pulse creates vibratory energy at the molecular level. This enables a release of toxins, excess ions, proteins etc. within the interstitial space.
Advanced models of LET instruments have additional electronic EM modalities that add important therapeutic benefits to the System: Multi-Chromatic, High Frequency Light Accessory (Eclipse) offers additional, local drainage effects; Pulsing Magnetic offers pulsed magnetic fields; Infrared Light therapy with ELF frequency modulates topical nutrients; Multi-Chromatic and Harmonic modulated lens with coherent light.
All Energies are Non-Thermal and safe for most persons. (see contraindications)
The EEF works with the sympathetic contractile forces of the lymph circulation as shown in a scientific study for a description of this mechanism of action; the Croley Study performed by Thomas Eugene Croley, PhD. Emeritus professor, Anatomy, Texas Women’s University.
The US FDA registration categories are extremely limited at this time. Companies must determine into which of the categories their device fits.
Lymphatic Enhancement Technology Instruments are state of the art technology for application on broad range of tissue congestion-based problems. Enhances and augments the functions of the lymphatic system as the detoxification channel for the body. Proven effective over 3 decades of users all over the world.

What LET is Not

A form of massage therapy or bodywork or an esthetics modality alone. LET may effectively be applied with or without hands-on techniques.
LET should not be defined as ‘lymphatic drainage’ nor limited in its professional scope of practice to the massage professions or others performing manual lymphatic therapy.
‘Lymphatic Therapy’ is not a standardized term and can refer to multiple types of treatments and treatment modalities around the world.
The term electro-lymphatic drainage is a generic term that is not proprietary to any specific product or company. LET is not “electro-lymphatic drainage or ELT.” This term emphasizes the use of gross electrical fields, rather than the subtle, EEF, sonic and acoustic waves and harmonics – rich energy fields of LET instruments. See technical section below.
It is not a standard electro-modality such as microcurrent, TENS transcutaneous neuro-muscular stimulation and electro-muscle stimulation through electrodes and electrified gloves.
LET is NOT ultrasound.
LET is not a Rife Machine or a PEMF Machine. Some of the PHIT modalities, options for the advanced LET models, may have energies like to those of pulsed – electromagnetic field or magnetic field units. (PEMF) However, these are described as such in the literature.


Not for use on persons with implanted medical devices.
Do not use in the presence of unexplained calf pain or over inflamed areas. (active blood clots with pain)
Do not use directly over any undiagnosed skin infections to avoid the spread of bacteria.
See precautions for use during medical treatment for cancer.
Do not use during pregnancy.

Precautions: Please turn machine OFF when removing or inputting head jacks.
Wear rubber/plastic gloves while using on others.
Avoid touching large metal objects while holding the heads or while on oneself.
Not for use in children under the age of 12.
