4. Common herbal remedies aren t always reliable
Many supplements claim to have immune-supporting powers and in the UK alone it’s estimated we spend more than £1billion per year on vitamins and supplements. At UCL’s School of Pharmacy, Dr Ronx looks at three popular herbal immune supplements - echinacea, garlic and elderberry. They dismissed the garlic and elderberry supplements right away as there was no concrete evidence these helped the immune system.
Only echinacea was reliable for immune-strengthening, with ‘reasonable’ evidence to support its effectiveness in treating symptoms of cold and flu, shortening the length of sickness by up to a day and a half. However, choose your echinacea carefully. Dr Ronx tests how much echinacea is actually in the products (they don t say which brands they tested). Some had almost none of the herb in them. They advise looking for the THR mark (Traditional Herbal Registration) for a reliable product that will make a difference.
