Selenium – Too Much of a Good Thing?
New Zealand soils are deficient in selenium and this can cause serious health problems for animals. A 500kg animal needs about 1mg selenium daily. There is no evidence that New Zealand adults need selenium supplements and this situation has been described as “a deficiency in search of a syndrome”.
A 52-year-old dairy farmer presented to her doctor with chronic aches and pains, lethargy, sore throat and painful swallowing. After some weeks of fruitless investigations she admitted to taking 0.5ml daily of a solution containing 5mg/ml of selenium, several times the recommended daily human dose. All of her symptoms disappeared once she stopped taking the supplement.
Despite the lack of proof for any deficiency syndrome in adults, local pharmacy leaflets stated “selenium is an essential trace element” and that “low levels of selenium are linked to a higher risk for cancer, cardiovascular disease, inflammatory diseases and other conditions associated with free radical damage, including premature ageing and cataract formation.”
It is quite clear that it would have been much safer for this woman to have taken a homeopathic selenium remedy and there would have been no risk at all of any toxicity from over dosage.

Animal Homeopathy
I know that homeopathy has been done to death but it crops up everywhere, even in the treatment of animals. People defend this delusion by claiming that the placebo effect does not work in animals, therefore any observed effect must be real. Any observed effect is clearly due to expectation on the part of the person administering the water, sorry, I mean the homeopathic remedy. An article in the Christchurch Press (March 12, 2004) described how Taranaki’s first qualified animal homeopath has gained an “advanced diploma of homeopathy”. She also has a BSc and it beggars belief that someone with that background can take up a pseudoscience such as homeopathy. This is what HL Mencken was referring to when he said: “How is it possible for a human brain to be divided into two insulated halves, one functioning normally, naturally, and even brilliantly, and the other capable of ghastly balderdash?”
I find it amusing reading such accounts because the clue to the belief system is usually contained in the article but is unrecognised. In this case the animals are described as “glowing with health in a way that suggests good feeding and love but their appearance is so striking it indicates there is another ingredient as well”. You guessed it — the other ingredient is homeopathy! It’s obvious that the animals’ condition is due to the “good feeding and love” and to claim otherwise is a delusion.
It would not in the least surprise me if the diploma of advanced homeopathy is NZQA approved.
Snake Oil Flunks for Snake Bite
Boonreung Bauchan was known in Thailand as the “Snake Man” and held a Guinness world record for spending seven days in a snake enclosure. The Mamba family of snakes are extremely venomous and when one of them bit him on the elbow he relied on a traditional herbal remedy and a shot of whisky. As we all know, herbal remedies are mostly placebos and should not be used for serious or life-threatening conditions and Boonreung is sadly no longer with us. Had he taken a proper antidote, his chances of survival would have been excellent.

Counsellors
If you get up in the morning and find your letterbox has been vandalised, don’t worry, counselling is available to help with your distress and grief. (Dominion Post March 6, 2004).
Following September 11, an estimated 9000 grief counsellors turned up in New York and one hotel was booked out by a single group of 350 counsellors. This absurd behaviour is of course defended by the counselling “industry” despite the existence of research that shows that many of such interventions are actually harmful. Counsellors defend their behaviour by claiming that it cannot be scientifically tested. For example: “People working from the scientific model want to measure outcomes. A lot of people would say, ‘I feel better’, but that doesn’t fit a scientific model.”
Such claims should be treated with complete contempt. This sort of reasoning could be used to justify the implementation of all sorts of quackery because it makes people “feel better”.
To put it bluntly, counselling is a placebo therapy. Third-party funding ensures that an industry has been able to develop. This has disempowered people from learning to deal with personal trauma by simply talking to a friend or other family members.
Hair Analysis
Last year I spent some time working in Westport and noticed an advertisement for hair analysis. Hair analysis does have a scientific basis but it has been taken over by quacks who offer all sorts of ridiculous assessments. When I got home I wrote to the address and sent hair from my wife Claire and my oldest daughter Eve, under their own names, and some hair from “Russell”. “Russell” was actually my daughter’s dog, a wheaten terrier.
For $40 I received a detailed four-page handwritten report and after reading it I felt quite mean because the writer’s sincerity was obvious. I have sent a copy of the letter to the Editor but will summarise the main findings. I see no value in exposing the writer because the letter was written in good faith but note that sincerity and good faith can go hand in hand with gullibility and foolishness. His findings were as follows:
Claire needs natural estrogen — “raspberry leaf” two tabs daily. Wormwood — 5 drops in water daily. Bach flower remedies — “Mimulus, Rock Rose”. Conscious deep breathing — practise six times daily. There was also a recommendation to have “faith” and consider the Bahai religion for that reason.
Eve had a systemic yeast infection. Recommended treatment: nystatin, aloe vera juice, Blackmores chewable tablets, wheatgerm capsules, super strength kelp, rescue remedy (Homeopathic), extra progesterone in the form of “wild yam cream”.
Russell also had a systemic yeast infection, and iodine deficiency. Recommended treatment: nystatin (oral antifungal agent), self heal tincture — 50 drops twice daily, herbal B vitamins — six tabs daily, super strength kelp — three tabs daily. Repeat hair analysis in three months.
It is easy to see that such a “scatter gun” approach to treatment would be bound to work in a well-motivated believer. I did not inquire as to the method of hair analysis but this is unimportant because any diagnostic method will work provided it is plausible and the treatment offered is congruent with the particular belief system. The homeopathic vet would no doubt approve of Russell’s diagnosis and treatment.
Shockwaves for chronic heel pain
High energy sound waves are now being used to treat various conditions such as tennis elbow and other painful areas such as the heel, knee and shoulder. It is claimed that 60-70 per cent of patients will gain relief from the treatment.
The same technology (extra-corporeal shockwave therapy or ESWT) is used to disintegrate kidney stones.
In the case of kidney stones there is no need for a randomised controlled trial (RCT) because it is obvious when a large stone has been broken down into smaller pieces.
When treating various painful conditions with no such “marker”, one has to be much more cautious and this therapy is crying out for a randomised controlled trial with a placebo group who would receive treatment administered when neither the patient nor the technician were aware that the machine was actually switched off. I predict that when such trials are carried out, there will be no advantage over placebo.
