Defining Placebo: the Saint Jude Thaddeus of Medical Terminology
I have recently begun calling the placebo effect the Saint Jude Thaddeus of Medical Terminology. This is not because placebo effects are miraculous – although they might sometimes seem to be – but because the placebo effect (or things even remotely connected to it) has gotten a bad rap for something it didn’t do. So what’s the connection to Saint Jude? Note this excerpt from a traditional prayer:
…faithful servant and friend of Jesus, the name of the traitor who delivered your beloved Master into the hands of the enemies has caused you to be forgotten by many, but the Church honors and invokes you universally as the patron of hopeless cases and of things despaired of…
So basically, Judas Thaddeus got a bad rap because of Judas Iscariot, so much so that there are now two ways of translating the name into English, Judas and Jude. So what does this have to do with placebo? First we define placebo and placebo effect:
a. a substance having no pharmacological effect but given merely to satisfy a patient who supposes it to be a medicine.b. a substance having no pharmacological effect butadministered as a control in testing experimentally or clinically the efficacy of a biologically active preparation.
a reaction to a placebo manifested by a lessening of symptoms or the production of anticipated side effects.
In Acupuncture For Chronic Low Back Pain, the authors reviewed clinical trials done to assess if acupuncture actually helps in chronic low back pain. The most important meta-analysis available was a 2008 study involving 6,359 patients, which “showed that real acupuncture treatments were no more effective than sham acupuncture treatments.”The authors then editorialized: “There was nevertheless evidence that both real acupuncture and sham acupuncture were more effective than no treatment and that acupuncture can be a useful supplement to other forms of conventional therapy for low back pain.”In Acupuncture For Chronic Low Back Pain, the authors reviewed clinical trials done to assess if acupuncture actually helps in chronic low back pain.

Dear writer (Mr. Ho), this controversy emerges from clinical trials comparing real and sham acupuncture. What you did not elaborate in your article is what is meant by ‘sham’ acupuncture? As acupuncture can be done not merely by piercing needles like in the photo, but also using laser, ultrasound, even with pressure or touch/ stroking the body surface. So, is the ‘sham’ acupuncture really sham? The modality of action is through neurophysicoendocrine pathway, by any modes of stimuli like stroking, piercing, etc. our body will react by showing the therapeutic effects like wellbeing, pain relieving, blood pressure downregulating (for hypertension, but not for normotensive)
First, they admit that pooled clinical trials of the best sort show that real acupuncture does no better than sham acupuncture. This should mean that acupuncture does not work – full stop. But then they say that both sham and real acupuncture work as well as the other and thus is useful. Translation: Please use acupuncture as a placebo on your patients; just don’t let them know it is a placebo.The authors trotted out the same conclusion after they reviewed an important German trial which also showed acupuncture to be merely a placebo.
In any randomized and blinded clinical trial of any mode of treatment for any condition, the finding that the treatment is no better than a placebo always leads to one conclusion only: It is therapeutically useless. Acupuncture, it would seem, is exempted from this rule.
In Chinese cosmology, all life is animated by a numinous force called qi, the flow of which mirrors the sun’s apparent “movement” during the year through the ecliptic. (The ecliptic is the imaginary plane of the earth’s orbit around the sun).
Moreover, everything in the Chinese zodiac is mirrored on Earth and in Man. This was taught even in the earliest systematised TCM text, the Yellow Emperor’s Canon Of Medicine, thus: “Heaven is covered with constellations, Earth with waterways, and man with channels.”
This means that if there is qi flowing around in the imaginary closed loop of the zodiac, there is qi flowing correspondingly in the body’s closed loop of imaginary meridians as well.These meridians run from head to toe to form a network interlinking 361 points on the skin. But why are there 361 points? Since the earth takes three minutes under 24 hours to rotate 360 degrees on its axis, the sun appears to revolve through 361 degrees on the ecliptic every 24 hours. Hence 361 points. This factoid alone is sufficient to nail down the acupuncture-astrology linkage.Since qi flows around in a closed loop, needles can be inserted at one of these points far removed from your site of pain to rechannel qi. If done well, this supposedly can cure your spot of trouble.
