Today on The Detail, Emile Donovan speaks to Mitchell, and to Mark Honeychurch from the Society for Science-based Healthcare, about the lax regulations and enforcement of natural medications in New Zealand. Our rules around medications and supplements is a matter of language. If you're selling a product which claims to have a therapeutic purpose - as in, something that will cure or correct an ailment - it falls under the Medicines Act of 1981, and must meet stringent requirements. In order to sell a pill which you say nullifies headaches, you have to prove it does, in fact, nullify headaches. However, if you're hawking a supplement which you claim is an innovative combination of ingredients which can boost the body's ability to stave off common ailments and reduce the likelihood of headaches, regulation is much thinner on the ground.
