Food and beverage products containing natural medicines should come with health warnings, according to the pharmacological organisation Australia's Adverse Drug Reaction Hotline . Geraldine Moses, director of the Hotline, told Channel News Asia that the time has come to realise that natural medicines are not as safe as they seem. They interact with prescription drugs and products containing herbal additives, and have many side effects. Furthermore, they are not really "natural": "Zinc tablets don't grow on trees and red clover tablets don't come out of the ground [...] they are just drugs"
