Herbal remedies are substances that come from plants. They come in various forms, such as capsules, teas, liquid drops or skin creams. You can get them at health food shops, supermarkets, pharmacies and from herbal practitioners.
Some may be referred to as 'supplements'. Others may be referred to as 'medicines', which means they aim to treat, cure or prevent a diagnosed health problem.
Often herbal remedies are part of alternative approaches to healthcare, such as Ayurvedic medicine and Traditional Chinese medicine (TCM).
There are lots of different types of herbal remedies that aim to help with different health conditions or help with your wellbeing. Some of the most common ones in the UK are:
Not all herbal remedies have been researched equally, and some have more scientific evidence to show how they work than others. However, many people find certain herbal remedies help them as part of self-care or managing symptoms.

Herbal medicines sold in supermarkets, pharmacists and health shops in the UK are licensed by the Medicines & Healthcare products Regulatory Agency (MHRA).

It should also have a registration number, starting with the letters 'THR'. You can find a list of which herbal medicines have been licensed on the Gov.uk website.
Some herbal ingredients are banned in the UK. You can find information on these on the Medicines & Healthcare products Regulatory Agency (MHRA) website.
Although herbal remedies are easily available to buy without a prescription, some may not be suitable for you, or could be harmful. For example if you:
“Plants and herbal remedies can be fantastic. Just check in with the pharmacy if you're taking medications to be sure they won’t negatively impact medications you're taking.”
Herbal practitioners play an established role in herbal medicine, Traditional Chinese medicine (TCM) and Ayurvedic medicine. But currently there are no rules around who can call themselves a herbal practitioner. You can practise without having any related experience or qualifications.
However, there are several voluntary registers which require certain standards of practice and education. So if you want to find a herbal practitioner, it's a good idea to find someone through one of these registers:
