The Best Herbs and Foods for a Liver Cleanse (Detox)
How the Liver Processes Heavy Metal Detox
Dr. Tinsay Woreta highlights the liver's essential role in detoxification:
"Your liver represents the human body's primary filtration system, converting toxins into waste products, cleansing your blood, and metabolizing nutrients and medications to provide the body with some of its most important proteins."
The liver’s detox work relies on two key pathways known as Phase 1 and Phase 2. These processes use molecules like glutathione to neutralize toxins, including heavy metals. The liver also produces around 1 liter of bile daily, which helps convert these metals into less harmful substances that can be safely excreted. Bile acts as a toxin carrier, moving heavy metals like mercury from the liver to the intestines for elimination through bowel movements.
However, there’s a catch: about 90–95% of these substances can be reabsorbed through enterohepatic circulation. This makes proper bile flow and sufficient dietary fiber critical to ensure toxins leave the body instead of being recycled. The liver also produces specific proteins, such as metallothioneins, to bind and manage heavy metals.
Unfortunately, detoxification isn’t without risks. Toxin exposure can damage liver cells, potentially leading to dysfunction or, in severe cases, organ failure. Heavy metals can also interfere with essential minerals in liver enzymes, disrupting normal liver activity.
When the liver becomes overwhelmed by toxins, its efficiency drops. Studies have linked factors like air pollution and chemicals such as PFAS to liver damage, including conditions like non-alcoholic fatty liver disease (NAFLD). Considering the liver handles over 500 functions daily, it’s clear that supporting this organ is vital to managing the growing toxic burden.
Dina Gavarieva, a naturopath at Neomed, emphasizes the importance of liver health:
"When we work to detox the body, many chronic illness symptoms subside, and it is easier to deal with infections and pathogens that thrive in toxic environments."
1. Cilantro
Known by other names like Chinese parsley or Mexican parsley, cilantro is the leafy part of the coriander plant, Coriandrum sativum. It’s a familiar herb in many American kitchens and is celebrated for its ability to aid liver function, particularly during heavy metal detoxification, thanks to its natural chelating properties.
How Cilantro Supports the Liver
Cilantro helps remove heavy metals from the bloodstream by naturally binding to them, which assists in cleansing tissues, organs, and blood. It also promotes bile production, a key player in digesting fats and flushing out toxins. On top of that, cilantro supports kidney function by enhancing the filtration of waste and toxins, reducing the risk of toxic buildup. These benefits have been backed by studies focusing on specific heavy metals.
Heavy Metals Cilantro Targets
Research suggests that cilantro can help eliminate heavy metals like mercury, lead, cadmium, arsenic, and aluminum [18, 19]. For instance, studies on animals have shown its potential for removing lead. A 2014 study reported that cilantro seed extract helped reduce lead-induced oxidative stress in rat brain tissues. More recently, a 2021 study highlighted cilantro’s ability to protect against oxidative stress and structural brain changes caused by lead exposure. Chris D'Adamo, Director of the Center for Integrative Medicine at the University of Maryland, commented:
"More studies would be helpful to confirm the findings, but there is some foundation to the claim being made about cilantro in light of this study and how we know it chelates heavy metals throughout the body."
Cilantro has also been shown to protect the liver and kidneys from cadmium-related damage. Animal studies revealed that supplementation helped restore kidney structure and reduced tissue damage caused by cadmium exposure.
Other Detox Benefits
Beyond its chelating abilities, cilantro is packed with antioxidants that shield liver cells from oxidative stress. This protection helps combat damage caused by free radicals, which are often linked to inflammation and aging [18, 19]. Traditionally, cilantro has been used to stimulate digestive fluids and relieve occasional indigestion. Additionally, research points to its potential in regulating blood sugar by improving insulin sensitivity, offering metabolic support during detoxification.
How to Use Cilantro
Cilantro is easy to include in your detox routine. Fresh cilantro can enhance salads, soups, and salsas, while frozen cilantro cubes are a convenient option for smoothies and detox drinks. For a more concentrated effect, liquid extracts or tinctures are widely available. Whether you’re tossing it into a salad or blending it into a smoothie, fresh cilantro is a simple way to support liver detox.
2. Milk Thistle
Milk thistle (Silybum marianum) is one of the most studied herbs when it comes to liver health. Its key benefits stem from silymarin, the active compound that typically makes up 65–80% of milk thistle extract. Silymarin is well-known for its ability to protect liver cells during detoxification, including the removal of heavy metals. Paired with cilantro’s metal-binding properties, milk thistle provides a complementary and research-backed boost to liver detox efforts.
How It Supports the Liver
Milk thistle works on several levels to promote liver health. Silybin, a component of silymarin, offers antioxidant and iron-chelating effects, while also reducing inflammation by blocking pro-inflammatory cytokines and NF-κB. It also helps prevent liver scarring, thanks to its antifibrotic properties. Silybin achieves this by reducing PDGF-induced cell transformation and lowering TGF-β levels, both of which contribute to fibrosis [24, 28].
Heavy Metals and Milk Thistle
Milk thistle aligns with the liver’s natural detox pathways by not only reversing liver damage but also preventing harmful metals from attaching to cell membranes. Research shows that it may help repair liver damage caused by heavy metals like mercury, arsenic, cadmium, and lead. Animal studies highlight silymarin’s ability to reduce liver injury and oxidative stress following exposure to toxic metals. Additionally, it acts as a barrier against toxins, blocking metals from binding to cells. For example, one study found it protected human male sperm cells from cadmium toxicity [7, 30]. Milk thistle has also shown potential for helping livers affected by industrial toxins like toluene and xylene.
Beyond Liver Detox
Milk thistle’s benefits extend beyond the liver. Its antioxidant properties also protect kidney cells, reduce inflammation in the gastrointestinal system and lymph nodes, and improve nutrient absorption. These effects contribute to overall detoxification and enhanced well-being.
Common Forms and Usage
Milk thistle is available in various forms, including capsules, powders, teas, and liquid extracts, making it easy to incorporate into daily routines. Capsules and tablets typically deliver 250–750 mg of ethanol-extracted silymarin, with standardized extracts often offering 200–400 mg for maximum benefit [24, 32]. Milk thistle powder can be mixed into smoothies, water, or tea, while liquid extracts provide a quick and convenient option. For a gentler approach, milk thistle tea works well, and fresh ground seeds can even be sprinkled on food. A standard dosage recommendation is around 420 mg daily for up to 3.5 years [31, 32].
3. Garlic
Garlic (Allium sativum) is a natural powerhouse when it comes to supporting liver health. Packed with more than 20 organosulfur compounds, it plays a key role in aiding liver detoxification, especially during heavy metal removal. With its antioxidant and anti-inflammatory properties, garlic stands out as one of nature's most effective tools for maintaining liver function.
How Garlic Supports Liver Detox
Garlic works its magic on the liver in several ways. When crushed, it releases allicin, a compound that activates liver enzymes responsible for sulphation, a process that prepares toxins for elimination. Beyond this, garlic increases levels of glutathione - a vital antioxidant in the liver - and stimulates the production of detox enzymes that help filter harmful substances from the digestive system. These enzymes, together with garlic’s sulfur compounds, bind to heavy metals in the bloodstream, making it easier for the body to eliminate them.
Heavy Metals Garlic Helps Remove
Garlic's sulfur compounds, such as S-allylcysteine and diallyl sulfide, are particularly effective at detoxifying heavy metals like lead, cadmium, mercury, and arsenic. Additionally, its mineral-rich profile - including selenium, calcium, magnesium, and zinc - supports toxin removal through urine. A 2012 study published in Food and Chemical Toxicology found that rats exposed to mercury, cadmium, and lead while consuming a diet with 7% raw garlic showed significant liver protection. Garlic was most effective against cadmium, moderately effective for mercury, and offered limited protection against lead.
More Than Just Detox
Garlic doesn’t stop at detoxifying heavy metals - it also promotes overall liver health. Research shows that men who ate raw garlic more than seven times a week had up to a 29% lower risk of developing fatty liver disease. Similarly, consuming raw garlic twice or more per week was linked to a 23% lower risk of liver cancer. In a 2020 clinical trial involving 98 individuals with non-alcoholic fatty liver disease, those who took 800 mg of garlic powder daily for 15 weeks saw significant reductions in liver enzymes (ALT and AST), LDL cholesterol, and triglycerides. Remarkably, 51% of the garlic group showed reduced liver fat compared to just 16% in the control group.
Best Ways to Use Garlic
For maximum detox benefits, raw garlic is the way to go. Crushing two cloves (around 2–5 grams) of raw garlic and consuming it in the morning is ideal, as this activates alliin, converting it into allicin for maximum potency. You can add crushed or chopped garlic to meals, mix it with honey, or steep it in hot water to make garlic tea. If raw garlic feels too strong, supplements like aged garlic extract (AGE) are a good alternative, offering protective effects against heavy metal toxicity. Interestingly, pickled garlic extract has been found to have stronger antioxidant activity than fresh garlic, making it another option for those who prefer milder flavors.

4. Dandelion Root
Often dismissed as a mere weed, dandelion root (Taraxacum officinale) has long been celebrated for its role in supporting liver health, especially during heavy metal detoxification. Historically used as a "liver tonic" for centuries, modern research confirms its ability to assist the body's natural detox processes.
How It Supports the Liver
Dandelion root works by enhancing the liver's detoxification pathways. It increases bile production, which helps flush out toxins, and acts as a natural diuretic, promoting the elimination of waste through urine. This combination aids both the liver and kidneys in their detox efforts.
A 2021 study highlighted dandelion root's protective effects on the liver. Researchers found that pretreatment with Taraxacum officinale extract reduced liver damage in laboratory models, primarily by minimizing oxidative stress associated with immune-related liver injury.
Broader Detox Benefits
Dandelion root's benefits extend beyond liver health. It also supports the gallbladder, kidneys, and blood, while promoting regular bowel movements. Packed with vitamin C and antioxidants, it helps protect cells from damage caused by heavy metals and other toxins. Additionally, its inulin content encourages the growth of beneficial gut bacteria, which plays a vital role in overall detoxification.
"Dandelion tea has been known to be a volume diuretic, gently nudging digestive and detoxification liver and bile systems into gear", says Nancy Geib, RD, LDN, a registered dietitian.
This diuretic action further amplifies its ability to aid in toxin elimination, making it a valuable addition to any detox routine.
How to Use Dandelion Root
Dandelion root is available in several forms, offering flexibility for daily use. A popular choice is dandelion root tea, which is caffeine-free and easy to prepare. Simply steep the root in hot water for 5–10 minutes.
If you're looking for a coffee alternative, roasted dandelion root is a great option. To make it, bake the root at 350°F for 10–15 minutes, then brew it like regular coffee.
For a more concentrated dose, tinctures and extracts are available. Alcohol-based tinctures can double as digestive bitters, while alcohol-free options cater to those who prefer them.
If you have access to untreated dandelions, you can harvest them yourself. Fresh leaves can be consumed in doses of 4–10 grams daily, while tinctures are typically taken at 0.5–1 teaspoon (2–5 mL) up to three times per day. Start with a smaller amount to gauge your tolerance, as dandelion root may have a strong laxative effect for some individuals.
5. Burdock Root
Burdock root (Arctium lappa) has long been celebrated for its ability to cleanse the blood and support the lymphatic system. Known as "gobo root" in Japan, where it’s cultivated as a vegetable, this herb has been used for centuries in Asia, Europe, and, more recently, North America for its detoxifying properties.
What sets burdock root apart during heavy metal detox is its ability to support multiple elimination pathways simultaneously, rather than focusing solely on the liver.
Liver Support Mechanism
Burdock root plays a key role in promoting liver health. It encourages bile production, which helps the liver efficiently flush out toxins. Additionally, it detoxifies the blood before it even reaches the liver. Its protective effects on liver cells are noteworthy, with research suggesting it may help prevent conditions like fatty liver disease by regulating fatty acid and lipid buildup.
Additional Detox Benefits
Beyond aiding the liver, burdock root offers a range of detoxifying benefits. It acts as a natural diuretic, helping the body expel toxins and excess water . As a lymphatic herb, it binds to and removes harmful waste - including heavy metals - through the lymphatic system . It can also stimulate sweating, offering yet another way for the body to eliminate toxins.
Packed with antioxidants like phenolic acids, quercetin, and luteolin, burdock root helps reduce inflammation and protects cells from damage during the detox process.
"Burdock root has been valued across continents for thousands of years for its ability to purify blood and cool internal heat. Internally and externally, it has potent anti-inflammatory and antibacterial effects on the human body." – Dr. Axe
Burdock root also has adaptogenic properties, which help regulate detox pathways and manage stress. Additionally, it supports gut health by nourishing beneficial bacteria like bifidobacteria, which are crucial for a balanced microbiome. These combined effects make burdock root a powerful ally in any detox regimen.
Typical Forms Used
Burdock root is incredibly versatile and can be added to your detox routine in several ways. Fresh burdock root can be eaten raw, cooked, pickled, or added to soups. To keep it fresh, clean and peel the root, then store it in a cool, dry place.
Burdock root tea, made by steeping dried root in hot water, provides a gentle, caffeine-free option for daily detox support. For a more concentrated dose, supplements are available in forms such as oil, dried powder, tinctures, or capsules. A common dosage is 1–2 grams of powder taken three times daily.
"Burdock root is a vegetable rich in antioxidants that people often use as a natural remedy for some skin conditions. It's available as a tea, root, powder, or extract and can be incorporated into recipes." – Ana Gotter
If you plan to forage for wild burdock root, be cautious. Avoid areas near roads, industrial sites, or places treated with pesticides, and ensure you correctly identify the plant to avoid mistaking it for toxic species like foxglove. Always consult with a healthcare provider or herbalist before using burdock root, especially if you have underlying health conditions or take medications.
