Best LIVER DETOX Herbs
1. Milk Thistle
Milk thistle has earned a solid reputation for supporting liver health, a benefit that’s been recognized for centuries and is now backed by modern research. Its unique properties make it a helpful addition to any liver detox routine.
Key Active Compounds
The liver-friendly effects of milk thistle stem from its primary active ingredient, silymarin. This compound, particularly its most active component, silybin, is a mix of potent flavonolignans[5][6][7]. Standardized milk thistle extracts typically contain 65%–80% flavonolignans. Thanks to enterohepatic recirculation, silymarin gets repeatedly exposed to the liver, leading to higher concentrations in liver cells compared to the bloodstream[4][7].
Primary Liver Health Benefits
Silymarin provides both antioxidant and anti-inflammatory effects[6]. These benefits help combat free radicals and reduce inflammation in liver tissue, aiding the liver’s natural ability to heal and regenerate. This combination makes milk thistle especially helpful for managing liver stress caused by toxins, medications, or certain lifestyle choices.
Common Forms of Use
You’ll find milk thistle in various forms, including powders, capsules, pills, and liquid extracts. Since silymarin has low water solubility, some supplements use enhanced absorption formulas for better effectiveness[8][10]. When selecting a milk thistle product, look for ones standardized to key compounds like silymarin or silibinin[9]. Options with phytosome milk thistle extract are also worth considering, as they improve bioavailability[9].
Precautions or Side Effects
Milk thistle is generally safe for most people. However, it’s a good idea to check with a healthcare provider before starting, especially if you’re on medications or have pre-existing conditions. Milk thistle may influence liver enzyme activity and could interact with certain drugs.
2. Dandelion Root
Dandelion root has been recognized for its liver-supportive qualities since the 16th century in China. This herb works alongside other natural detoxifiers to help maintain a healthy liver. Let’s break down why dandelion root plays such a key role in liver health.
Key Active Compounds
Dandelion root is packed with bioactive compounds like taraxasterol, chicoric acid, chlorogenic acid, and tetrahydroridentin B. Taraxasterol helps regulate inflammation and oxidative stress, protecting liver cells from potential damage[11]. Meanwhile, tetrahydroridentin B activates Nrf2 (nuclear factor erythroid 2-related factor 2) in liver cells, which enhances the liver's detoxification abilities. Together, these compounds create a powerful synergy to support liver function.
Primary Liver Health Benefits
Dandelion root offers multiple benefits for liver health. It promotes bile production, which helps the body clear toxins more efficiently. Additionally, it boosts antioxidant enzyme levels in the liver while reducing the production of harmful reactive oxygen species (ROS)[13]. Research in animal studies has shown that dandelion root can prevent liver fibrosis, reduce inflammation, and minimize oxidative stress[11][12]. Another notable benefit is its ability to combat alcohol-induced oxidative stress, which may lower the risk of liver disease or failure[13].
Common Forms of Use
You can find dandelion root in various forms, including tinctures, teas, tablets, and capsules. Dandelion root tea is especially popular - simply steep the root in hot water for 5–10 minutes, then strain and enjoy[14]. Dosages vary depending on the product, so always check the specific instructions provided[14].
Precautions or Side Effects
Stick to a daily intake of 1–3 grams to avoid potential allergic reactions, particularly if you're sensitive to plants in the daisy family[13].
3. Artichoke Leaf
Artichoke leaf joins the ranks of herbs like milk thistle and dandelion root in supporting liver detoxification. This ancient Mediterranean herb, long appreciated for its role in digestion, has become a modern go-to for liver health thanks to its rich array of beneficial compounds.
Key Active Compounds
Artichoke leaf is packed with compounds that promote liver function. Among the most notable are cynarin and luteolin [16]. It also contains mono-caffeoylquinic acid, dicaffeoylquinic acid (including cynarin and chlorogenic acid), caffeic acid, and flavonoids like luteolin-7-β-rutinoside, luteolin-7-β-D-glucoside, and luteolin-4-β-D-glucoside [18]. Together, these substances create a robust antioxidant system that helps safeguard liver cells.
Primary Liver Health Benefits
Artichoke leaf extract offers several benefits for liver health. It stimulates bile production, aiding the liver in flushing out toxins [15]. Its phenolic compounds help shield liver cells from damage and can reduce elevated liver enzymes, which are often a sign of inflammation or injury [17].
In a 2018 study involving 90 individuals with non-alcoholic fatty liver disease, participants who took 600 mg of artichoke extract daily for two months showed improved liver function [15]. These benefits stem from its ability to lower reactive oxygen species, reduce lipid peroxidation, and boost glutathione peroxidase levels [18]. Additionally, artichoke extract supports liver tissue regeneration and reduces inflammation [15], while cynarin and chlorogenic acid provide further antioxidant protection against oxidative stress [19].
Common Forms of Use
Artichoke leaf extract is available in various forms, including capsules, gelcaps, and liquid concentrates [22]. Typical dosages range from 320–640 mg taken up to three times daily [20][21][22]. When choosing a supplement, look for one standardized to a particular concentration of cynarin or other active compounds [16].
Precautions or Side Effects
Although artichoke leaf extract is generally safe for most adults, some groups should approach it with caution. It’s not recommended for those who are pregnant, nursing, under 18, or dealing with severe liver or kidney disease [15]. Always follow the dosage instructions on the product label and consult a healthcare provider before starting any new supplement, especially if you have existing medical conditions or take other medications [20][21][22].

4. Turmeric
Turmeric has been a staple in Ayurvedic medicine for centuries, often used to address liver health. Modern research backs this up, highlighting its potential to support liver function [23]. Let’s take a closer look at the compounds behind these benefits.
Key Active Compounds
The liver-supporting effects of turmeric come from its curcuminoids - primarily curcumin, along with demethoxycurcumin and bisdemethoxycurcumin. These compounds make up 1%–6% of turmeric extract [23]. Curcumin stands out for its ability to neutralize reactive oxygen species and prevent lipid peroxidation, which bolsters its antioxidant properties [24].
Primary Liver Health Benefits
Curcumin is known for its anti-inflammatory and antioxidant effects, which help protect liver cells from toxins and improve bile flow. These actions can reduce inflammation and lower elevated liver enzyme levels [26]. The growing interest in curcumin is evident in its market growth - it was valued at over $73 million in 2021 and is expected to surpass $155 million by 2029 [28].
Common Forms of Use
Turmeric is available in various forms, but oral supplements are often the most effective due to better absorption. While using turmeric as a spice in food and drinks is common, turmeric extracts provide a more concentrated source of curcumin. For best results, take turmeric with food, especially meals containing healthy fats like eggs or vegetable oils, and add black pepper to significantly boost absorption. Some specialized formulations are designed to further enhance bioavailability. If you’re new to supplementation, start with a low dose of a few hundred milligrams and gradually increase it if no side effects occur [29]. Consistent, long-term use is recommended for managing fatty liver issues [30].
Precautions or Side Effects
Although turmeric is generally safe, rare cases of liver injury have been linked to herbal supplements containing turmeric or curcumin, especially at high doses or in enhanced-absorption formulations. People with pre-existing liver conditions may face a higher risk [27].
There’s also a potential concern with turmeric supplements combined with black pepper, as this pairing can alter how turmeric is processed in the body [25]. Be aware of warning signs of liver injury, such as yellowing of the skin or eyes, dark urine, nausea, vomiting, fatigue, abdominal pain, or loss of appetite [27].
Keep in mind that turmeric should be used to complement - not replace - medical treatments and lifestyle changes [29].
5. Licorice Root
Licorice root has been a staple in both Eastern and Western medicine for its ability to support liver health [32]. Packed with bioactive compounds, this herb has shown potential in reducing liver damage by boosting the body's antioxidant and anti-inflammatory defenses [32].
Key Active Compounds
The liver-supporting properties of licorice root come from its rich mix of bioactive compounds. The standout among these is glycyrrhizin (also known as glycyrrhizic acid), a triterpene glycoside celebrated for its anti-inflammatory and antiviral effects [32]. Other notable compounds include liquiritin, liquiritigenin, isoliquiritigenin, licochalcone A, and glycycoumarin. Isoliquiritigenin, for instance, has been shown to inhibit certain cancer cells, including hepatoma [31]. Meanwhile, glabridin has demonstrated anticancer potential by reducing the expression of growth factor receptors [31]. Together, these compounds work in harmony to enhance liver detoxification processes.
Primary Liver Health Benefits
Licorice root helps the liver by calming inflammation and strengthening antioxidant defenses [32]. Animal studies have revealed that licorice can restore glutathione (GSH) levels in the liver, suppress TNF-α secretion, and prevent fat buildup in the livers of subjects fed a chronic alcohol diet [32]. Research also shows that glycyrrhizin and licorice extracts can help protect the liver from damage caused by chemotherapy, acetaminophen, prescription drugs, obesity, and ischemia [35].
In a clinical trial involving 52 Iranian women with nonalcoholic fatty liver disease, a daily dose of 1,000 mg of licorice for three months led to greater weight loss and reduced ALT levels compared to a placebo group [35]. These findings highlight licorice's potential as a natural option for liver health management.
Common Forms of Use
You can find licorice root in various forms, such as teas, capsules, extracts, and even topical applications. For those concerned about potential side effects, deglycyrrhizinated licorice (DGL) is a safer option, as it removes glycyrrhizin. DGL supplements are particularly suitable for individuals with high blood pressure or low potassium levels and can be used for up to four months [37][39]. When selecting a licorice supplement, pay attention to quality and sourcing. Most licorice on the market - over 90% - comes from Glycyrrhiza uralensis [33].
Precautions or Side Effects
While licorice root offers numerous benefits, using it responsibly is crucial. As a food, licorice is generally safe, but consuming too much can lead to serious issues like irregular heartbeat or even cardiac arrest [37]. Experts recommend limiting intake to no more than 5 grams daily for extended periods. The FDA also advises individuals over 40 to consume no more than 2 ounces per day for up to two weeks to avoid complications such as irregular heart rhythms [36][38].
"Black licorice is definitely safe to eat in small amounts... However, it is important to realize that black licorice is more than just candy. It contains glycyrrhizic acid, which can cause swelling and high blood pressure and deplete potassium and other electrolytes that may cause a cardiac arrhythmia or arrest."
- Diane Calello, Executive Medical Director of the New Jersey Poison Control Center [38]
People with high blood pressure, heart disease, or kidney conditions should steer clear of licorice [37]. Additionally, licorice can interact with medications like corticosteroids, blood pressure drugs, blood thinners, and diuretics [34][37]. Pregnant women should also exercise caution - consuming roughly 250 grams per week during pregnancy may increase the risk of preterm delivery [36].
Licorice root remains a powerful ally in promoting liver health and detoxification, but it’s essential to use it wisely to avoid potential risks.

While this chart gives a snapshot of each herb’s profile, understanding the safety and proper use of these supplements is just as important. Always weigh potential benefits against risks when considering herbal remedies.
Important Safety Considerations
Herbal supplements for liver health should be approached with care. As Dr. Paul Kwo from Stanford University aptly puts it, "Just because something is natural does not mean it is safe" [41].
For instance, a 2022 case study reported acute liver injury in a 36-year-old woman after consuming a liver detox tea that included dandelion root [41]. Dr. Tinsay Woreta, a hepatologist at Johns Hopkins, also warns that "These unregulated supplements may vary in composition and lack thorough clinical testing" [1].
Choosing the Right Approach
Considering the liver’s vital role in detoxification, experts recommend focusing on a balanced approach that prioritizes safety. Many advocate for a food-first strategy. Kristin Kirkpatrick, a registered dietitian at Cleveland Clinic, advises: "As a dietitian, I would suggest actual food over a product that promises to detox your liver. The liver does a good job doing this on its own, as long as you treat it well" [41].
For those opting for supplements, deglycyrrhizinated licorice (DGL) is often seen as a safer option, and turmeric should be used cautiously - especially when paired with black pepper.
With nearly 100 million Americans affected by liver-related conditions [40], consulting a healthcare provider before starting any herbal regimen is essential. Personalized advice is key, as individual responses to these supplements can vary significantly.
Conclusion
The five herbs covered earlier offer valuable support for liver health by protecting cells, encouraging bile flow, and calming inflammation [40][42]. Milk thistle, thanks to its silymarin content, helps shield liver cells from damage while promoting regeneration - making it particularly helpful for conditions like alcoholic hepatitis and non-alcoholic fatty liver disease [40][42]. Dandelion root works as a natural diuretic, enhancing bile flow to aid in toxin removal [40][42]. Artichoke leaf contributes to better digestion and bile production through its cynarin compound [40]. Turmeric brings anti-inflammatory and antioxidant properties through curcumin, which helps reduce fat buildup in the liver and stimulates bile production [40][3][42]. Lastly, licorice root helps reduce inflammation and offers protection to liver cells [2].
With millions worldwide dealing with liver conditions [40][2], finding effective and safe support is essential. However, it’s important to note that herbal and dietary supplements are linked to up to 20% of liver injury cases [45]. Data from the Drug Induced Liver Injury Network reveals an increase in such cases, rising from about 10% to over 16%, attributed to these products [44]. These statistics highlight the importance of selecting high-quality supplements and using them responsibly.
Dr. Melissa Young from the Cleveland Clinic advises caution when choosing herbal products: "You only want to use herbal supplements from companies that you know are doing their due diligence. Look for brands that do independent testing of both their raw materials and the finished materials and who use good sourcing practices. Some herbs are very powerful, and if you're taking medication or living with certain health conditions, they can hurt more than they help" [46]. For those looking to support liver detox, Mahoney World LLC offers TUDCA & NAC supplements designed to assist in liver detoxification and ease symptoms during cleansing protocols.
Consulting a healthcare provider before starting any herbal regimen is crucial, especially since approximately 65% of individuals in the United States and Europe with liver diseases already use herbal supplements [2]. Drug-herb interactions can lead to serious complications, making professional guidance essential.
Incorporating these herbs into a balanced lifestyle - one that includes nutrient-rich whole foods, regular physical activity, proper hydration, and reduced alcohol consumption - can further support liver health [40][43]. Considering that the liver handles over 500 important functions daily, combining quality supplements with professional advice can help optimize its performance.
