Plants That Remove Toxins From The Body

Written by: Pard Bharaj

Unfortunately, pollutants are all around us‚ÄĒin the air, water, prescription medicines and even our food‚ÄĒmaking it inevitable that some will enter our bodies. Managing this accumulation of toxins is important for maintaining a healthy immune system.

The human body has a natural detoxifying system, with the liver, colon, and kidneys. The liver prevents toxins in food from entering the bloodstream, the colon expels toxic chemicals, and the kidneys filter the blood, removing toxins through urine.

However, the body's detoxifying system can become overwhelmed by the volume of toxins and sometimes it needs a helping hand. Fortunately, several plants may assist in detoxification. In this article, I will discuss eight plants, review the scientific evidence on their effectiveness in removing toxins, and explain the mechanisms by which they are believed to achieve this.

I encourage readers to review the "references and further reading" section at the end of the article where I have provided summaries of relevant scientific studies.

7 Plants That Remove Toxins From the Body:

1. Spirulina:

Spirulina, a cyanobacterium commonly known as blue-green algae, is well known for being one of the world's most nutrient dense foods. It is Packed with vitamins, minerals, and powerful antioxidants, it holds a well earned position at the top of the superfood category. 

Spirulina's ability to chelate heavy metals and assist in their removal from the body is well-documented through various preclinical studies. This detoxification property is primarily due to specific compounds within Spirulina that have a strong affinity for binding heavy metal ions, as well as improving liver health.

Limited other studies show that it can also be effective and counteracting the toxic effects of various environmental pollutants, including arsenic, cadmium, carbon tetrachloride, deltamethrin, fluoride, hexachlorocyclohexane, iron, lead, lindane, and mercury and  mycotoxins - although more research is required to confirm these findings.

2. Chlorella:

Chlorella is a single-celled, green algae that has been well researched for its health benefits, particularly in detoxification. It is rich in nutrients. Chlorella supports liver health and the body's ability to flush out harmful toxins. Its unique properties allow it to bind with heavy metals and other contaminants, facilitating their removal from the body.

  • Heavy Metals: Chlorella has a high affinity for heavy metals such as lead, mercury, and cadmium, effectively preventing their reabsorption and aiding in their expulsion from the body.

  • Radiation and Chemotherapy: Chlorella is beneficial for cancer patients undergoing radiation or chemotherapy. It protects against ultraviolet radiation treatments and helps eliminate radioactive particles. Studies indicate that chlorella can also help maintain immune system function, reducing the frequency of respiratory infections and flu-like illnesses during such treatments.

3. Wheatgrass:

Wheatgrass, a nutrient-dense superfood, has a number of studies showing its efficacy for detoxification and better blood. 

One of the key components of wheatgrass is chlorophyll, which has a molecular structure similar to hemoglobin. This high chlorophyll content can help cleanse the liver and bloodstream by neutralising and binding to toxins, and facilitating their removal from the body. Additionally, wheatgrass contains a range of antioxidants such as flavonoids and phenolic acids, which combat oxidative stress and protect cells from damage. This detoxifying effect is further enhanced by wheatgrass's ability to boost the activity of liver enzymes responsible for detoxification processes.

Wheatgrass can improve blood health by enhancing hemoglobin production and increasing red blood cell count. This is particularly beneficial for conditions like anemia and thalassemia.

4. Barley Grass:

Barley grass, a young shoot of the barley plant, is a nutrient-rich superfood known to be packed with essential vitamins, minerals, amino acids, and antioxidants.

Scientific studies highlight barley grass's ability to detoxify harmful substances. Research has shown that its antioxidants, including superoxide dismutase (SOD) and flavonoids, combat oxidative stress and protect cells from damage. Also, barley grass's dietary fibre content supports gastrointestinal health by promoting regular bowel movements and expelling waste products.

Furthermore, barley grass has been found to help eliminate mycotoxins, harmful compounds produced by moulds, and other environmental pollutants. Its comprehensive nutritional profile, including beta-glucans and phenolic acids, contributes to its potent detoxifying properties.

5. Cilantro:

Cilantro is a herb traditionally used to aid digestion, reduce inflammation, and treat gastrointestinal issues.

Studies show that coriander can potentially enhance mercury excretion, especially after dental amalgam removal, and decreases lead absorption in bones by mitigating the inhibition of the delta-aminolevulinic acid dehydratase (ALAD) enzyme. Rich in antioxidants, coriander supports liver health and combats oxidative stress, crucial for detoxification. However, a trial with children exposed to lead found coriander extract as effective as a placebo in increasing renal excretion of lead, with improvements attributed to better diet during the intervention.

There is evidence that using cilantro with chlorella can enhance heavy metal detoxification. In summary, coriander shows promise as a natural detoxifying agent, particularly for mercury and lead. While results are promising, some evidence suggests otherwise, indicating the need for more research to verify coriander's effectiveness.

6. Dandelion:

Dandelion, scientifically known as Taraxacum officinale, is valued in traditional medicine for its potent detoxifying properties. This herb supports the liver and kidneys, vital organs in the body's natural detoxification process.

Dandelion has hepatoprotective effects which can enhance liver function by increasing bile flow, which helps eliminate toxins from the body. Dandelion's diuretic properties facilitate the removal of toxins by increasing urine output, thus supporting renal function and the overall detox process.

A study from Poland found dandelions to be pure and free from heavy metals and other toxins, but they did contain a significant amount of biological contaminants. This emphasises the importance of thoroughly washing dandelions before consumption, especially those collected from busy areas, to reduce health risks.

7. Milk Thistle:

Milk thistle, known scientifically as Silybum marianum, is a herb traditionally used for its liver-protecting benefits.

  • Liver Protection: The active compound in milk thistle, silymarin, and its component silybin, are potent antioxidants which aid in detoxifying the liver. They help reduce liver enzyme levels and improve insulin resistance, which is beneficial for overall liver function and recovery.
  • Anti-inflammatory and Antioxidant Properties: Silymarin has anti-inflammatory properties that reduce liver inflammation and oxidative stress, further supporting liver detoxification and protection from environmental toxins.

Milk thistle potentially offers benefits for liver detoxification and protection, supported by its therapeutic compounds. However, the potential risk of mycotoxin contamination in supplements calls for vigilant quality checks and more rigorous research to fully establish its safety and efficacy in detoxification.
