Traditional herbal remedies - quality and safety matters

Locally, traditional herbal remedies are a popular and trusted form of complementary healthcare. As with any type of health product, it is important to consider the quality and safety of these remedies.

People who suffer from chronic pains or illnesses are often the targets of unscrupulous dealers who may peddle adulterated "herbal" remedies containing undeclared prescription medicines such as steroids. It is dangerous to take these potent medicines without the advice of a healthcare professional.

As adulterated products are often made under poor manufacturing conditions with no quality control, they may not contain the right dosages of the medicines or even the correct ingredient and can seriously harm your health. Furthermore, the adverse effects of taking substandard or adulterated products may not be immediately evident, and irreversible damage may have been done by the time it is discovered.

Consult your doctor, pharmacist, or traditional Chinese medicine (TCM) physician if you need help in managing a chronic medical condition. Do not entrust your health to unscrupulous dealers and dubious products.

Here is a selection of cases to illustrate the types of illegal health products that have been detected.

Potent steroids and medicines found in traditional herbal remedies

A woman in her 50s took “纯天然草药 Natural Herbs” for two months for general wellbeing but ended up with Cushing’s syndrome, a serious steroid-induced condition. The product claimed to have “no steroid and mercury added”, and was labelled to be “suitable” to treat a wide range of conditions including knee pain, itchy skin, internal injury and stroke. Contrary to the claim, laboratory analysis found the tablets contained a potent steroid, dexamethasone. The woman had purchased the tablets through a relative.

In another case, a woman in her 60s who turned to "PHQ 1001 Khasiat Penawar Herba Qaseh Serata Herb" in search of relief from chronic knee pain and consumed it for a few months found herself gaining weight and developing a puffy face. She also experienced rapid pain relief from the product, an effect brought about by the potent painkillers that were illegally added to the product. Doctors diagnosed her to have diabetes and Cushing’s syndrome. She had purchased the product through a social media platform.

"PHQ 1001 Khasiat Penawar Herba Qaseh Serata Herb" was marketed as a traditional herbal remedy for a variety of medical conditions such as pain, impotence, kidney diseases and stroke. However, it was tested by HSA to contain undeclared potent medicinal ingredients, including dexamethasone (a potent steroid), griseofulvin (an antifungal), piroxicam and paracetamol (painkillers).

In another case, a man in his 70s suffered discomfort in his eyes a day after he took “辣木草药丸” (“La Mu Cao Capsules”) for pain relief. The capsules, bought through a friend, contained dark brown powder and were packed in an unlabelled transparent bag. They also came with a leaflet printed in Chinese stating the product name and claiming that the capsules contained herbal ingredients including Moringa seeds (“辣木籽”), cordyceps (“冬虫夏草”) and panax ginseng (“高丽参”).

However, laboratory analysis found that the capsules contained several potent medicinal ingredients, including prednisolone (a potent steroid), amoxicillin (an antibiotic), diclofenac (an anti-inflammatory painkiller), and paracetamol (painkiller).

Things to keep in mind when you purchase herbal medicines or remedies

• Be cautious of exaggerated claims and over-promises. Health products that promise “quick cures” and “easy solutions” to medical problems are often not backed by scientific evidence. Unscrupulous dealers may produce and sell health products with undeclared potent medicinal ingredients to achieve a “quick cure” effect. Taking such health products can be extremely harmful to your health.

• Buy from reputable sources such as a pharmacy, established retail store/chain or their authorised e-commerce websites. As a general rule, be cautious when purchasing health products from unfamiliar places or unknown online sources, even if they are recommended by well-meaning friends or relatives. You cannot be certain what these health products contain, and where and how they were made.

• Make informed choices about the health products that you will be consuming.

1. A company that is instrumental in placing a Complementary Health Product (CHP) in the market may voluntarily notify HSA of the product supplied, or to be supplied, in Singapore. This is based on companies’ self-assessment of the relevant supporting information to ensure their product meets the appropriate safety, and quality and labelling standards. More products that meet the relevant requirements based on companies’ self-assessment of relevant supporting information will be added to the database over time. The inclusion in this database should not be misconstrued as HSA's endorsement of these products. You can refer to the list of CHP that are voluntarily notified with HSA here.

2. Get advice from your doctor, pharmacist of TCM physician if you are unsure which health product suits you.
