One of the common ways to defend pseudomedicine is to show how less bad it is than real medicine. The usual method of doing this is to exaggerate the number of deaths in hospitals and compare the fabricated number with the number of people who die, for example, in chiropractors' offices. No thinking person needs to have the absurdity of this sort of comparison pointed out to them, but the lie is usually compounded by claiming that real doctors don't care and are doing nothing about the carnage. One particularly insidious piece of sophistry is to (mis)quote numbers from a research project commissioned by the Australian government as evidence that no research is being done. I have seen this same research project, with the same deliberately misquoted numbers, used to prove that nothing is being done in the USA either. The argument then goes on to say that it is unreasonable for real medicine to complain about pseudomedicine before solving all the problems related to patient survival in hospitals. If the airlines refused to spend money on safety practices until the road toll had been reduced to zero then nobody would be prepared to fly anywhere, but this is exactly the sort of argument being used by the quack promoters. It's like saying: "You're not perfect, so I won't even try to be good".
Another approach is to claim that real medicines have not really been tested because all possible combinations of medications have not been subjected to clinical trials. Testing all possible interactions between only two drugs is not possible because of the infinite range of dosage ratios, so it is in a sense true to say that any combination of drugs is an untested prescription. It is true to say it, but it doesn't mean anything.
One of the differences between medicine and the alternative is that in medicine people generally know how much of a medication is being taken, what it does and, more importantly, how and why it does it. Knowing what part of the body is affected by a chemical allows for possible interactions and adverse events to be predicted, and when there is some doubt only vital medications are advised and all others are contraindicated. I will give three examples from my own experience and that of some acquaintances.
The "combinations aren't tested" argument is a straw man - it is a false statement of the opposing position. More than that, though, it is hypocritical when coming from supporters of "alternative medicine". Walk into any health food store and look at the range of "natural" and "herbal" products on the shelves. You will see row upon row of bottles containing mixtures of ingredients, with many ingredients occurring in several different mixtures to "treat" or "relieve" different ailments, and some of the ingredients being sold separately to cure yet more complaints. It is not uncommon to hear someone say that they are taking many different herbs, vitamins and supplements.
If it is bad for real doctors to prescribe untested combinations of drugs in a situation where the individual dosages and actions of the drugs are known, how much worse is it to take a mixture of medicines where it is impossible to know the actual dose taken of any component or even to know what all the components are or do and where nothing has been shown to work for anything anyway.
