Just because herbal medicines are natural, it does not mean that they are completely safe. Some of nature's strongest poisons are 'natural' rather than 'man-made' chemicals.

As with any medicine, people taking herbal preparations need to follow the instructions carefully. All licensed herbal remedies will be supported by an in-pack PIL (patient information leaflet). Customers must follow the recommended dose and take note of any cautions, such as whether they are suitable for pregnant women or children. People taking other medication need to consult the pharmacist before using a herbal product as there may be interactions.

If anyone does experience any problems, you should advise them to stop taking the herbal product and refer them to the pharmacist for fur ther advice.

One herb to watch out for is St John's wort (hypericum), which is commonly used by people who are feeling low or depressed. This herb has been found to interact with a number of prescribed drugs, including oral contraceptives. You should refer anyone enquiring about this herb to the pharmacist.
