Traditional herbal remedies

People have been taking herbal remedies for centuries, but since May 2011 herbal remedies come under special regulations.

Herbal products such as St John’s wort, echinacea and black cohosh need to be registered with the medicines regulator MHRA and can only be sold for the conditions for which they are registered.

The MHRA says the scheme is designed to address problems with poor quality herbal remedies, some of which were found to be adulterated or contained the wrong herb. Some products also failed to provide information about side effects and contra-indications with other medicines or give warnings for pregnant women or people with certain medical conditions.

The scheme was tightened further from May 2014. All manufactured herbal medicines now have to be authorised by the MHRA in order to be sold and supplied lawfully in the UK.

What Traditional Herbal Registration means

Unlike licensing for mainstream medicines, registration doesn't mean a herbal remedy has been tested and proven to actually work.

It does mean the MHRA is satisfied the product is made to good quality standards with appropriate labelling and a product information leaflet. It also means the herb has been used in traditional remedies for more than 30 years.

Registered products carry a special THR leaf logo.


Research by the MHRA found that many people thought that 'natural' ingredients were safer to take than other medicines. The regulator stresses this is not the case, emphasising that herbal products can have a very potent effect.

Other sources of herbal products

The THR scheme covers products bought in UK shops and from reputable online retailers. As with unregulated internet sites claiming to sell mainstream medicines, the MHRA warns against buying herbal remedies online, unless from a trusted UK retailer.
