Singapore HSA Warns Public: Herbal Remedies Containing Hidden Steroids Pose Serious Health Risks
The Health Sciences Authority (HSA) in Singapore has issued a critical public advisory warning against the consumption of certain herbal remedies after laboratory tests revealed they contain potent steroids and anti-inflammatory painkillers. The products—“Setia Herba” and previously identified remedies like “D’sihat Herba Gout & Sendi”—pose significant health risks, including hormonal imbalances, organ damage, and severe allergic reactions.
This alert underscores a growing global concern: the unregulated herbal supplement market often hides dangerous pharmaceutical ingredients. Here’s what the public needs to know about the risks, symptoms, and how to protect themselves.
HSA’s Latest Warning: What Was Found in These Herbal Remedies?
Urgent Public Advisory: The HSA has detected dexamethasone (a potent corticosteroid), prednisolone (another steroid used to reduce inflammation), and diclofenac (a nonsteroidal anti-inflammatory drug, or NSAID) in “Setia Herba”. These ingredients are not listed on the product labels and were identified through mandatory testing by the HSA.
Why This Is Dangerous
- Unregulated Dosage: Consumers have no way of knowing the exact amount of steroids or painkillers they’re ingesting, risking overdose or prolonged exposure.
- Hormonal Disruption: Steroids like dexamethasone and prednisolone can suppress the immune system, increase blood sugar levels, and cause adrenal insufficiency if used long-term.
- Organ Damage: Diclofenac, while effective for pain relief, can damage the stomach lining, kidneys, and liver with prolonged use.
- Allergic Reactions: Some individuals may experience severe allergic responses to undocumented ingredients, leading to hospitalization.
This Isn’t the First Time: A Pattern of Contaminated Herbal Products
This warning follows a 2023 HSA alert about two other herbal products—“D’sihat Herba Gout & Sendi” and “Yanwo Chongcao Yanyin Qinfei Huatan Dan”—which were also found to contain undisclosed potent medicinal ingredients. In that case, one consumer was hospitalized, and another experienced serious adverse effects.
The recurring issue highlights a critical gap in Singapore’s supplement regulation: herbal products are not subject to the same rigorous pre-market approval process as pharmaceuticals. While the HSA conducts post-market testing, the burden of proof often falls on consumers to report adverse reactions.
Recognizing the Symptoms: How to Know If You’ve Been Affected
If you’ve consumed any of the flagged herbal remedies and experience the following symptoms, seek immediate medical attention:
- Steroid-related symptoms:
- Unexplained weight gain or redistribution of fat (e.g., “moon face,” buffalo hump)
- High blood pressure or blood sugar spikes
- Mood swings, anxiety, or depression
- Increased susceptibility to infections
- Diclofenac-related symptoms:
- Stomach pain, nausea, or vomiting
- Black or tarry stools (sign of gastrointestinal bleeding)
- Swelling or fluid retention
- Kidney or liver function abnormalities
- Allergic reactions:
- Rash, hives, or itching
- Swelling of the face, lips, or throat
- Difficulty breathing or wheezing
Note: Symptoms may not appear immediately. Chronic use of these hidden ingredients can lead to long-term health complications.
How to Protect Yourself: 5 Critical Steps
- Stop Using Suspected Products Immediately. If you’ve consumed any of the flagged herbal remedies, discontinue use and consult a doctor.
- Check for HSA Warnings. The HSA maintains a list of recalled or adulterated products. Bookmark this page for future reference.
- Avoid “Natural” ≠ “Safe” Assumptions. Herbal supplements are not automatically safe. Look for products with third-party certifications (e.g., NSF, Informed-Choice) and avoid those making unverified health claims.
- Consult a Healthcare Provider Before Use. Even if a product is legal, discuss it with your doctor—especially if you have pre-existing conditions or take prescription medications.
- Report Adverse Reactions. If you experience side effects after using a herbal product, report it to the HSA via their online portal. Your report can help prevent others from being harmed.
Expert Perspective: Why This Matters Beyond Singapore
Dr. Natalie Singh, a board-certified internist and public health specialist, explains the broader implications:
“This HSA alert is a stark reminder that the herbal supplement industry operates in a regulatory gray area. Unlike pharmaceuticals, these products aren’t required to disclose their full formulation, even if they contain active pharmaceutical ingredients. Consumers often assume ‘natural’ means ‘safe,’ but the reality is far more complex. The presence of dexamethasone—a drug typically prescribed for severe conditions like asthma or cancer-related inflammation—highlights the potential for these products to cause more harm than the ailments they claim to treat.”
“For individuals with chronic conditions, such as arthritis or gout, the temptation to try ‘natural’ alternatives is understandable. However, without proper oversight, these products can interact dangerously with prescribed medications or exacerbate underlying health issues. The key message here is caution. If a product seems too good to be true—it probably is.”
FAQ: Your Questions Answered
Q: Are these products still available for sale in Singapore?
A: The HSA has likely taken enforcement action against the distributors of these products. However, counterfeit or unregulated versions may still circulate. Always purchase supplements from licensed pharmacies or reputable retailers.
Q: Can I test my herbal supplements for hidden ingredients?
A: Currently, there is no consumer-accessible testing method for hidden pharmaceuticals in supplements. The HSA relies on mandatory testing and public reports. If you suspect a product is contaminated, report it immediately.
Q: What should I do if I’ve been taking these products long-term?
A: Seek medical evaluation without delay. Long-term use of undocumented steroids or NSAIDs can lead to irreversible damage. Your doctor may need to monitor your adrenal function, blood pressure, or organ health.
Q: Are there safe alternatives for joint pain or inflammation?
A: Yes. For mild joint pain, consider:
- Physical therapy or low-impact exercise (e.g., swimming, yoga)
- Approved over-the-counter NSAIDs (e.g., ibuprofen) under medical supervision
- Dietary supplements with evidence-based safety profiles, such as glucosamine/chondroitin (consult your doctor first)
Avoid products making unsubstantiated claims or lacking regulatory approval.
Key Takeaways: Protecting Your Health
- The HSA has identified hidden steroids and painkillers in multiple herbal remedies, posing serious health risks.
- Symptoms of exposure can mimic other conditions—seek medical advice if you’re concerned.
- Herbal supplements are not regulated like pharmaceuticals. Proceed with caution.
- Report suspicious products to the HSA to help prevent others from being harmed.
- When in doubt, consult a healthcare provider before using any supplement.
A Call for Stricter Regulations
This incident raises critical questions about Singapore’s supplement regulation framework. While the HSA’s proactive testing is commendable, experts argue for mandatory pre-market approval for herbal products containing active pharmaceutical ingredients. Until then, consumers must remain vigilant.
As Dr. Singh notes, “The onus shouldn’t be solely on consumers to navigate this risky landscape. Regulators must act swiftly to close loopholes, and manufacturers must prioritize transparency over profit. Until then, the safest ‘natural’ remedy is informed skepticism.”
