5 Herbal Supplements That Can Damage the Liver: What You Need to Know
Herbal supplements have become extremely popular as natural substitutes for traditional medication in recent years. For anything from better digestion to increased energy, many people use these cures. However, it might be extremely erroneous to assume that "natural" always equates to "safe.". Serious liver damage, such as cirrhosis, hepatitis, and even liver failure, has been connected to certain herbal supplements.
An essential organ, the liver is in charge of digesting foods, metabolizing medications, and cleansing the body. The liver is frequently the first organ to break down the active ingredients in herbal supplements. Regretfully, several of these substances have the potential to be harmful to the liver, particularly when consumed in high concentrations or for an extended length of time.
The following five herbal supplements have been linked to liver damage:
1. Kava Kava
Kava kava, derived from the root of the Piper methysticum plant, is often used to reduce anxiety and promote relaxation. While it has been traditionally consumed in Pacific Island cultures, its use in concentrated supplement forms has raised concerns. Studies have linked kava kava to severe liver toxicity, including hepatitis and liver failure. The exact mechanism is unclear, but it’s believed that certain compounds in kava, called kavalactones, may interfere with liver function. As a result, several countries have banned or restricted its sale.
2. Comfrey
Comfrey (Symphytum officinale) has been used for centuries to treat wounds, bruises, and joint pain due to its anti-inflammatory properties. However, comfrey contains pyrrolizidine alkaloids (PAs), which are toxic to the liver. These compounds can cause irreversible damage, leading to conditions like hepatic veno-occlusive disease (VOD), where the small veins in the liver become blocked. While topical use may be less risky, oral consumption of comfrey is strongly discouraged.
3. Green Tea Extract
Green tea is widely celebrated for its antioxidant properties and potential health benefits. However, concentrated green tea extract, often marketed for weight loss, has been linked to liver injury in some cases. The high levels of catechins, particularly epigallocatechin gallate (EGCG), can overwhelm the liver when taken in large doses. Symptoms of liver damage from green tea extract include jaundice, abdominal pain, and elevated liver enzymes. Moderation is key, and it’s best to avoid high-dose supplements unless supervised by a healthcare professional.
4. Black Cohosh
Black cohosh (Actaea racemosa) is commonly used to alleviate menopausal symptoms such as hot flashes and mood swings. Despite its popularity, there have been numerous reports of liver damage associated with its use. The exact cause remains unknown, but some researchers suspect that certain compounds in black cohosh may trigger an autoimmune response or directly damage liver cells. If you’re considering black cohosh, consult your doctor, especially if you have a history of liver issues.
5. Chaparrall
Chaparrall, also known as creosote bush (Larrea tridentata), is often promoted as a detoxifying agent and antioxidant. However, it contains nordihydroguaiaretic acid (NDGA), which has been linked to liver toxicity. Cases of hepatitis and liver failure have been reported in individuals using chaparrall supplements. Due to these risks, the U.S. Food and Drug Administration (FDA) has issued warnings against its use.
How to Protect Your Liver
While herbal supplements can offer health benefits, it’s crucial to approach them with caution. Here are some tips to minimize the risk of liver damage:
Consult a Healthcare Professional: Always talk to your doctor before starting any new supplement, especially if you have pre-existing liver conditions or are taking medications.
Stick to Recommended Doses: More isn’t always better. Follow the recommended dosage and avoid long-term use unless advised by a professional.
Choose Reputable Brands: Not all supplements are created equal. Opt for products that have been third-party tested for quality and safety.
Monitor for Symptoms: Be aware of signs of liver damage, such as jaundice (yellowing of the skin or eyes), dark urine, abdominal pain, or unexplained fatigue. If you experience any of these, stop using the supplement and seek medical attention immediately.
The Bottom Line
Herbal supplements may seem like a harmless way to support your health, but they can carry significant risks, particularly for your liver. The supplements listed above are just a few examples of natural remedies that can have serious consequences. Always prioritize safety by doing your research, consulting a healthcare provider, and listening to your body. Remember, when it comes to your health, natural doesn’t always mean safe.
By staying informed and cautious, you can make better choices for your well-being and protect one of your body’s most vital organs—your liver. Stay connected with us
