"what makes you qualified to say so" A strong sense of scepticism. I start by asking myself "what would make this work; what's the mechanism". I thought initially the idea was that a baby chews on the amber. But it seems the claims are based on the amber relasing something or other. Here's a good pro amber explanation http://www.mamapukeko.co.nz/howamberworks.html Well written though this is, it sets the alarm bells ringing ("If you are sceptical that it won't work then we don't have concrete proof to convince you otherwise"). So I use Google to check out the science. 5 minutes of doing this shows there is no evidence that amber works at all, other than I guess as a placebo or as something that gives parents a sense of empowerment. The most compelling theory is that body heat releases succinic acid, which is meant to be a natural anti-inflammatory. But this seems bogus to me and indeed it transpires Amber needs to be heated to 200 degrees to release SA. There's a good balanced and sceptical discussion here http://scepticon.wordpress.com/2011/02/21/amber-teething-beads-a-few-points-to-consider/ Key quote: "Based on the complete lack of plausibility on any level of efficacy any potential for harm, however small, must tip the balance of this equation away from the use of this product" I agree. It seems bogus to me.
