PHNOM PENH, Cambodia (AP) — I sported those purple round welts on my body long before Michael Phelps was born. OK, so Phelps made the world aware of cupping by showing his marked muscular shoulders before diving into the pool at the Rio games.
But cupping, and a similar treatment known as coining, has been practiced in East Asia for centuries. I grew up with them. My mother made sure of that.
Phelps, the 31-year-old U.S. swimming star, was seen with purple circles dotting his shoulder and back before his first race at the Olympics. The circles were caused by the ancient Chinese treatment, in which he is a great believer.
It involves pressing glass or plastic cups to the area of discomfort and either applying heat or suction to create a vacuum. The suction causes the large hickey-like marks.
Another similar treatment is coining. The principle is the same: press a large metal disc with an attached handle on the area of discomfort. While cupping is virtually unknown in the rest of the world — and dismissed by doctors educated in Western medicine as hocus pocus — it is commonplace in China, Cambodia, Vietnam and Myanmar as a cure for ailments as varied as fever, tuberculosis, rheumatism and muscular pain.
Associated Press reporter Sopheng Cheang, who grew up in Cambodia, narrates his lifelong experience with coining and cupping.
I remember, some 40 years ago (I am 46), when I fell sick, my mother always did coining on me. She would rub coconut oil on my skin and then push the coin all over, leaving rows of welts. It scared me. I would cry and sometimes run away. But my mother would say: "Be patient! It will take only a few minutes to complete and it will hurt just a little bit, like an ant bite."
So I would let her, and it usually helped.
In my generation, most people did coining when they had fever including my relatives, siblings and neighbor. Cupping became popular later.
Now when I have a fever, flu, headache or other problems I go to a neighborhood "cupping spa" and get both done. Not that I don't trust medicines. But I also believe in cupping and coining. Got it done just last month for my fever, which wasn't coming down with medicines and injections. One session of cupping and the fever was gone.
The procedure was done in a well-illuminated room with one small bed and a wall fan. I took off my shirt and lay down on my stomach so the practitioner could work on my back, first by rubbing oil and then using the coin. After 15 minutes or so, she told me to turn over and so she could work on my chest. The same procedure was followed with cups as I dozed off.
But there's a rule to coining and cupping — no alcohol or bath for three hours before and five hours after the treatment.
It is popular in the countryside because it is cheap and most Cambodians are poor, and not every village has hospitals or clinics. Ironic, since health spas in the U.S. charge a few hundred dollars for the service. Here we pay the equivalent of $3 for an hour-long session.
Even Prime Minister Hun Sen has touted the benefits of coining and cupping. He has told journalists that his wife Bun Rany does it on him when he is sick.
In ancient times, cupping was used to get rid of blood and pus when treating skin abscess, but it has been expanded to treat tuberculosis and rheumatism. Because cupping was widely used in Chinese folklore culture, the technique was inherited by modern Chinese practitioners. It is established as an official therapeutic practice in hospitals all over China.
The U.S. National Institutes of Health says on its website that cupping "is considered generally safe for healthy people when performed by a trained health professional." While saying the placebo effect may account for some claimed health benefits, it also cites recent research that found it may be an effective short-term treatment for chronic neck and lower-back pain.
I ran into Sok Pheakdkey, a 39-year-old driver at a local construction company, at a cupping clinic where he had undergone treatment for fever.
"Now I feel I am fully recovered. Do you see the sweat coming from my head and back? That means the fever is gone," he said. He said the medicines he bought from a pharmacy brought his fever down, but only for a while.
"I don't mean to say that I don't trust medicines. But in my experience the best way to treat these illnesses is coining and cupping. My body seems to be addicted to this type of treatment even though it hurts," he said.
The Cambodian Health Ministry does not advocate cupping, and warns that it could be a health risk.
Health Ministry spokesman Ly Sovann told me that the practice is not known to cure any illnesses, and in fact can be dangerous for people with high blood pressure or heart problems. Still, the practice is not banned in the country because it is almost a way of life for Cambodians, he said.
"My advice is that Cambodia people should start changing their habit. They should consult physicians or doctors first if their illness is something related to high blood pressure and heart attack. Then after they talk with the doctor, of course they can do coining or cupping if they prefer," he said.
