Pesticides in Tea: Why Organic Tea Matters

When we think of our favorite cup of tea as a source of comfort and relaxation, we rarely consider that it may contain not only antioxidants but also traces of chemical substances. Yet numerous studies show that pesticides used on tea plantations can leave residues on the leaves, which may then pass into the infusion and affect the body.

How Pesticides Get into Tea

During the cultivation of tea bushes, fungicides, insecticides, and other chemical protection agents are commonly used. Some of these substances settle on the leaves and may not be completely removed during processing.

The review “The Bitter Side of Teas: Pesticide Residues and Their Impact on Human Health” shows that such residues can transfer into the beverage and may potentially contribute to hormonal and reproductive disorders or even increase the risk of cancer.

One study on organochlorine pesticide residues in tea found that concentrations in some samples exceeded the maximum permissible limits in China of 0.2 mg/kg. Another study examining 42 pesticides in Tieguanyin tea included a risk assessment and revealed that some substances could pose a health risk when consumed regularly.

It is also worth noting findings on pesticide residues in both herbal and conventional tea blends. The study “Pesticide Residues in Common and Herbal Teas Combined with Risk Assessment” indicates that such substances are present in a wide range of teas, although their concentrations are often below the permitted limits.

What Health Risks Are Involved?

• Hormonal and reproductive disorders: some pesticides can act as endocrine disruptors.
• Neurotoxicity and effects on the nervous system: organophosphates such as chlorpyrifos can inhibit enzymes responsible for nerve signal transmission, which is associated with cognitive and neurological effects.
• Toxic accumulation: with regular consumption, small doses of pesticides can accumulate in tissues, especially in the case of persistent compounds such as certain organochlorine pesticides.

Why Organic Tea Is More Than Just Marketing

• Reduced pesticide exposure: a meta-analysis by Barański et al. published in 2014 showed that consuming organic products is associated with lower levels of pesticide residues in the human body.
• More antioxidants and less burden on the body: according to “Health Benefits and Reduced Pesticide Exposure,” organically grown spices, herbs, and tea often contain higher concentrations of beneficial compounds and lower levels of heavy metals.
• Environmental sustainability: avoiding chemicals helps plantations maintain soil fertility, reduce erosion, protect water resources, and preserve biodiversity.

Our Approach at Helis Tea

At Helis Tea, we strive to ensure that every stage of production is safe for both people and the planet, from hand-picking the leaves to completely avoiding synthetic pesticides.

By restoring abandoned plantations and using environmentally friendly methods, we not only offer a clean and pure beverage but also contribute to the revival of ecosystems. We have already obtained organic certificates and laboratory analyses from an Israeli laboratory confirming that our tea is 100% organically pure. These certificates can be viewed in the “About Us” section.

Tea will not make us immortal. But one thing is certain: the fewer chemical substances it contains, the more natural and beneficial it can be. In this sense, organic tea is not an illusion but a real alternative to conventional beverages with their invisible additives.
