By Breaking Belize News Staff: A Chinese-inspired herbal tea manufactured in El Salvador could soon become available in Belize, with its developers promoting it as a natural supplement for people living with kidney disease and several other chronic health conditions.
The product is marketed under the name Té She Yin Cheng, also written as Té Sheyin Cheng, and was developed by natural-medicine practitioner She Yin Cheng, who has lived and operated businesses in El Salvador for several decades.
During an interview, Cheng said the product is based on principles of Chinese herbal medicine and has gained recognition among doctors and patients in El Salvador. He said his goal is to introduce it to Belize, where it could be distributed while offering another option to people experiencing kidney-related health problems.
The product’s Salvadoran registration can be independently confirmed. The Superintendencia de Regulación Sanitaria lists “Té de Hierbas Naturales,” registration number 76657, as an active nationally manufactured product under the brand Té She Yin Cheng. The registration was issued on February 26, 2025, and is valid until February 26, 2030. It is classified as “tea and herbs for infusion,” with a risk classification of C, and is registered in 200-gram and 400-gram presentations.
The registration confirms that the product is legally registered in El Salvador as a tea or food infusion. It should not, however, be interpreted as independent confirmation that every medical benefit being promoted has been clinically proven.
Promoters report growing interest among doctors
Saúl Roberto Alvarado, a Salvadoran medical representative for the product, said his role is to present information about the supplement to doctors, particularly general practitioners who may recommend nutritional or herbal supplements.
Alvarado described the product as a combination of herbs forming a traditional Chinese-style formula. He claimed that some patients diagnosed with chronic kidney disease had experienced improvements in their symptoms and laboratory results while using the tea alongside their regular medical treatment.
He also attributed possible benefits relating to creatinine levels, blood sugar, fatty liver, uric acid, blood pressure, kidney stones and electrolyte balance. These remain claims by the product’s representatives and have not been independently confirmed through published clinical research.
The product is being presented as a complement to conventional medical care, rather than a replacement for medication, dialysis or other treatment prescribed by a doctor.
Small observational study underway
Documents supplied by the product’s representatives include a one-page report bearing the name and clinic stamp of Salvadoran urologist Dr. Guillermo Antonio Martínez Romero. Online Salvadoran medical directories also identify Martínez Romero as a urologist and endoscopic specialist practising in Sonsonate and Santa Ana.
The document describes an ongoing nine-month observation involving 25 patients diagnosed with chronic renal insufficiency. The patients reportedly included people with hypertension, Type 2 diabetes and other conditions affecting kidney function.
Preliminary observations listed in the document include:
- Improvement in gastrointestinal symptoms, weakness and general discomfort;
- Stable fluid and electrolyte levels;
- Creatinine levels that reportedly remained stable during follow-up testing; and
- A reported average creatinine reduction of approximately 1 milligram among most participants.
The report says longer-term evaluations are continuing.
However, the document does not provide individual laboratory reports, a control group, the stages of kidney disease among participants, statistical analysis, information about other medications being used or evidence that the observations have been published and peer-reviewed. The preliminary results therefore cannot establish that the tea caused the reported changes.
What is in the tea?
The packaging lists ingredients including:
- Green tea, or Camellia sinensis;
- Chamomile, or Matricaria chamomilla; and
- Soy, or Glycine max.
The manufacturer describes it as a preservative-free, natural herbal supplement. People with soy allergies should note that the product contains soy.
The instructions recommend adding one tablespoon of the mixture to approximately 12 ounces of boiling water, simmering it over low heat for three minutes, allowing it to rest for another two to three minutes and then straining it.
The recommended serving is two cups daily—one after breakfast and another after the evening meal.
The packaging also recommends a low-fat, high-fibre diet and advises users to avoid red meat, dairy products, processed foods, carbonated or sugary beverages, alcohol and tobacco.
Testimonials posted on Facebook
Facebook searches found several accounts promoting the tea, including pages called Té Sheyin Cheng and Té Natural Sheyin Cheng – El Salvador.
The pages have published videos and posts labelled “real testimonials,” “visiting one of our patients” and statements claiming that customers have experienced a better quality of life.
Other promotional posts refer to it as a “miracle tea” and market it for kidney failure, diabetes, fatty liver and hypertension.
The publicly indexed Facebook material did not provide enough information to independently confirm the patients’ diagnoses, complete laboratory histories, medications, dietary changes or whether their reported improvements were assessed by independent medical professionals. The testimonials should therefore be treated as personal accounts rather than clinical proof.
Medical supervision strongly advised
People with kidney disease should consult a nephrologist or other qualified doctor before taking the product. They should not discontinue medication, postpone dialysis or alter a prescribed treatment plan based on promotional claims or testimonials.
The National Kidney Foundation warns that some herbal products can interact with medications, worsen kidney disease or contain ingredients that are unsafe for people with reduced kidney function.
The United States National Institute of Diabetes and Digestive and Kidney Diseases similarly advises people receiving dialysis not to take over-the-counter supplements without first consulting their healthcare team, as certain vitamins, minerals or herbal ingredients may be harmful.
