Ingredient Restrictions for Herbal Supplements in Malaysia: How to Check NPRA's Prohibited and Restricted Lists

In Malaysia, any herbal and plant-extract product presented in a "small-unit dosage form" such as capsules, tablets, powders or liquids, used to supplement the diet or maintain health, falls within the scope of a health supplement or natural product, regulated by the Ministry of Health's National Pharmaceutical Regulatory Agency (NPRA). The core obligation is a single sentence: registration must be completed before sale, obtaining a registration number beginning with MAL, and every herbal ingredient in the formula must pass the prohibited/restricted list check — you cannot add whatever you like.

Classification and attribution of herbal products

The same herb takes a different registration route depending on the "claim": if presented for traditional use (such as traditional Chinese medicine, Ayurveda, or Jamu), it is classed as a natural product / traditional medicine, with a MAL number ending in "T"; if positioned to supplement the diet and maintain health functions, it is classed as a health supplement, with a MAL number ending in "N". Both must be registered with NPRA; the difference lies in the assessment route and the claims available. When it is stuck at the border between food and drug, you can apply for NPRA's product-classification service to clarify the attribution.

How to check prohibited and restricted ingredients

NPRA does not list "usable herbs" as a single whitelist, but manages them through an "exclusion list + case-by-case review" approach. Before drafting a formula, be sure to compare against the following official documents:

Examples of the pregnancy-contraindicated category include horsetail (Equisetum arvense), hellebore (Helleborus spp.), evening primrose (Oenothera biennis), passionflower (Passiflora incarnata) and nux-vomica (Semen Strychnos nux-vomica); this list is not exhaustive and is updated from time to time, so always rely on the latest official text.

Three red lines that are easy to cross

First, endangered and protected species: if the formula contains animal or plant sources on the CITES list (such as some orchids, rhino horn, pangolin, etc.), it must comply with Appendix 6's provisions on protected/endangered ingredients, and registration will be refused if legal proof of source cannot be provided.

Second, adulteration: herbal and traditional medicine categories have the most adulteration cases in Malaysia, commonly found to be illegally spiked with steroids (such as dexamethasone), antihistamines, sibutramine, or Western erectile-dysfunction drugs. Once discovered, NPRA will cancel the registration, add it to the list of unregistered adulterated products, and publicise it. Claiming "pure herbal yet astonishingly potent" is often a sign of adulteration.

Third, prohibited ingredients and dosage-form restrictions: any substance listed in the schedule of the Poisons Act may not be used as a health-supplement ingredient; fluoride in any form may not be used in health-supplement formulas; and single-ingredient oral vitamin K preparations are also not allowed. These boundaries apply equally to compound products containing herbs.

Label and quality requirements

After registration is approved, the label of a herbal supplement must clearly state the MAL registration number and bear a Meditag anti-counterfeit hologram label; products containing animal-source ingredients (such as gelatin capsule shells) must state the source and add a safety warning such as "Keep out of reach of children / Jauhkan daripada capaian kanak-kanak." On the quality side, it must comply with heavy-metal and microbial limits and provide a finished-product Certificate of Analysis (COA); efficacy claims may only fall within the range of maintaining health and may not claim to treat disease.

Frequently asked questions (FAQ)

Q: My product is just a compound tea bag of a few herbs — does it also need registration? Yes. Products presented as herbal and intended for oral supplementation or traditional efficacy — whether tea bags, powders or capsules — must be registered with NPRA for a MAL number before sale; selling without a MAL number is illegal.

Q: Where can I check whether a particular herb can be used? First compare against the prohibited/restricted lists in DRGD Appendix 8 and the Natural Products Guide, then use the Product Search on the NPRA website to check whether the ingredient has been registered or previously accepted; if you cannot find it, go through the case-by-case review route to confirm — do not assume it is usable.

Q: Are the rules the same for imported herbal supplements? The classification and prohibited/restricted standards are the same, but imported products must be applied for by a local Product Registration Holder (PRH), with documents such as a free-sale certificate and GMP prepared; if the ingredients contain endangered species, legal proof of source must also be attached.

Q: Does labelling "all natural" mean it is safe and I can make any claim? No. Natural does not equal risk-free; some herbs are themselves toxic or contraindicated in pregnancy; and all claims must comply with the health-supplement definition and may not imply disease-treating efficacy, or the product will be required to be taken down or have its registration cancelled.

Self-check list

• [ ] Compared against DRGD Appendix 8 and the Natural Products Guide, confirming no prohibited ingredients and restricted ingredients not exceeding limits
• [ ] Checked pregnancy-contraindicated herbs and added the corresponding warning on the label
• [ ] For endangered/protected species, prepared legal proof of source
• [ ] Completed NPRA registration, obtained a MAL number and affixed Meditag
• [ ] Efficacy claims fall only within maintaining health, not treating disease

Summary: For herbal supplements in Malaysia, the point is not "can it be sold" but "do the ingredients pass NPRA's prohibited/restricted check, and is there a MAL number." Checking the lists first and registering afterwards is far more cost-effective than being caught with adulteration or prohibited ingredients after launch.
