Herbal medicines and homeopathic remedies

You should always consult your medical team before taking any herbal medicines or homeopathic remedies.

Although herbal medicines and homeopathic remedies are usually made with natural ingredients, they should still be treated with caution. They can directly cause potentially harmful effects or interfere with other treatments you’re having. 

Herbal medicines

Herbal medicines are made from plant parts, such as roots, leaves and flowers.

Many people think that because herbal medicines are natural, they’re safe to take. However, they can have potentially harmful effects either directly, by causing a bad reaction or side-effects, or indirectly, by interfering with your standard treatment. 

For this reason, herbal medicines should be treated with caution and you should always consult your healthcare team before taking any herbal medicines.

Herbal medicines that are mass produced and sold over the counter, do need to be licensed and granted a tradition herbal registration (THR). 

However, it’s important to note that herbal medicines made specially for an individual or bought online or by mail order, don’t need to be licensed. These medicines run the risk of being unlicensed, substandard, fake or even contaminated.

Herbal medicines that are licensed in the UK come under the Traditional Herbal Medicines Registration Scheme. This provides specific safety and quality standards. Manufacturers registered with the scheme are also legally obliged to monitor the safety of their products once they’re on the market.

If a herbal product is found to contain potentially harmful ingredients, or which interacts with conventional medicines, details are posted on the Medicines and Healthcare Products Regulatory Agency (MHRA) website.

So if you want to try a herbal medicine, it’s best to look for THR on the packaging. But, be aware that a THR-labelled product:

• is intended only for minor conditions that can be self-medicated and don’t need medical supervision, such as coughs, colds or general aches and pains
• could be harmful when used for more serious conditions, especially if you delay seeking medical advice
• isn’t necessarily completely safe for everyone to take.

Also, its claims are based on traditional usage, not on evidence of the product’s effectiveness.

Homeopathic remedies

Homeopathic remedies are made from highly diluted substances that claim to cause the body to heal itself. However, there’s no scientific evidence to support this, and so it’s considered to be a complementary or alternative medicine.

As a result, homeopathy is usually provided privately. There’s no legal regulation of homeopathic practitioners in the UK nor of the substances that these remedies may contain.

As with herbal medicines, some homeopathic remedies may contain substances that aren’t safe or may interfere with your standard treatment. Always speak to your doctor if you’re thinking of trying some.

The MHRA has recently introduced a new scheme for regulating homeopathic remedies, though only a few are now ‘licensed’. Remedies licensed and manufactured under the scheme will be in a container that’s labelled with a Homeopathic Registration (HR) number.
