Monday’s medical myth: take an aspirin a day after you turn 50
By Michael Tam, University of New South Wales
Aspirin is a historical marvel. It’s been manufactured for more than a century and is still in widespread use. No other medication can claim as many different narratives and uses as this analgesic – it’s been known as:
- A traditional medicine – aspirin-like treatments, based on salicylate, have been derived from plants such as willows for millennia
- An international blockbuster – at the turn of the twentieth century, aspirin was one of the few effective treatments for fever and pain, and was wildly popular (and profitable)
- A hazard to children – aspirin was recognised in the 1980s as a potential cause of childhood death
- A modern wonder-drug – aspirin has been resurrected as an important and inexpensive medication for the prevention and treatment of heart attacks and strokes. Continue reading

Comment: Homoeopathy, ethics and controversy
Comment to the article “Homeopathy isn’t unethical, it’s just controversial” by Jon Wardle, published in The Conversation.
To be frank, it is really quite simple. Homoeopathy isn’t “controversial”. It does not work. There is no good empiric evidence that it does, plenty of empiric evidence that it doesn’t, and entirely lacks scientific plausibility.
There is a misunderstanding of evidence-based medicine that supportive evidence of an intervention study in an RCT is equivalent to evidence of effectiveness. This is not true. If you do 20 perfectly run RCTs on inert substances using the standard for statistic significance at P < 0.05, you would expect that 1 study would demonstrate a statistically significant result. The point is, RCTs are only really valid when taken in the context of the pre-text probability of the intervention. As has been mentioned many times before, for homoeopathy (the specific intervention) to be true, we must overturn our knowledge of physics and chemistry. Continue reading
