If you’re anything like me, tea is more than a warm drink.
It’s part of your rituals — your grounding, your healing, your winter coziness, your morning reset, your nightly unwinding.
Tea has always felt safe to me… until I stumbled across a video talking about pesticide residues, contamination, and even hidden pharmaceuticals in certain teas. At first, I brushed it off — the internet loves drama. But something in me needed to know for sure.
So I started digging.
Not into opinions.
Not into fear-based viral graphics.
But into actual lab reports, recalls, and independent investigations.
And what I found shocked me enough that I completely cleaned out my tea drawer and rebuilt it from scratch.
This is the post I wish I had when I started.

Why Tea Can Be More Contaminated Than You Think
Tea leaves aren’t rinsed before drying.
They aren’t washed before steeping.
And when you pour boiling water over them, everything on the leaf — good or bad — ends up in your cup.
There are four major issues that kept popping up in my research:
Pesticide residues — especially on conventional teas, and sometimes even on organic ones due to cross-contamination.
Heavy metals — related to soil quality and growing regions.
Microplastics — from some tea bags, especially “silky” pyramid bags.
Undisclosed pharmaceuticals — extremely rare, but it has happened (and recently).
Let’s break down what I found brand by brand.
Tea Brands That Raised Red Flags in My Research
Before I continue, let me be clear:
I am not calling any company “toxic.”
What I am doing is sharing what independent labs and regulatory agencies have documented — so you can make informed choices.
Himalayan Pain Relief Tea — Undeclared Prescription Drugs
This was the most alarming finding because it wasn’t about pesticides — it was about actual hidden pharmaceuticals.
Multiple regulatory agencies, including the U.S. FDA, issued broad recalls after tests found diclofenac (a prescription anti-inflammatory) and dexamethasone (a strong steroid) inside Himalayan Pain Relief Tea.
None of these drugs were listed on the label.
Why this matters:
These medications can seriously affect the liver, kidneys, blood pressure, immune system, and blood sugar.
They interact with countless medications.
They can cause major side effects if used long-term without supervision.
This was an immediate, unquestionable avoid completely.
Celestial Seasonings — Multiple Pesticide Residues (Historic Tests)
In a 2013 independent Eurofins analysis commissioned by a consumer group, 91% of Celestial Seasonings teas tested positive for multiple pesticides, with several samples exceeding U.S. limits, including pesticides banned in some regions.
Celestial Seasonings disputed the results — but they have never published full, transparent, third-party lab data to clearly settle the issue.
For me, that lack of updated transparency is a red flag.
Teavana (Starbucks) — Pesticides in 100% of Samples Tested (Historic)
When independent labs tested a wide range of Teavana teas, they found:
100% contained pesticide residues
77% exceeded European safety standards
Some contained pesticides not approved for tea in certain regions
Starbucks later shut down all Teavana retail locations.
To date, there has been no clear public contaminant testing published for Starbucks-branded teas.
This is another “lack of transparency” category.
Big Conventional Tea Brands: Lipton, Twinings, Tetley, Bigelow, Trader Joe’s, Stash
A Canadian news investigation tested multiple popular black and green teas:
9 out of 10 brands contained multiple pesticide residues
Only one brand tested clean in that sample
Lipton, Tetley, and Twinings were among those with residues
Greenpeace also reported multiple pesticide residues (3–17 types) in some Lipton samples from other countries
To be fair:
These tests were snapshots — not ongoing monitoring
Companies sometimes change suppliers
Laws and standards differ by region
But very few of these companies publish current third-party pesticide, heavy metal, or microplastic testing
So the concern isn’t “this tea is dangerous” — it’s:
“I prefer brands that openly demonstrate their testing, not ones that ask me to trust without data.”
Yogi Tea — Organic Brand, Still Had a Major Recall (2024)
This one surprised me because Yogi is often seen as “safer” due to organic certification.
However, in 2024, over 54,000 boxes of Yogi Organic Echinacea Immune Support Tea were recalled because they contained pesticide residues above FDA limits.
This doesn’t make Yogi terrible — it makes them human.
But it does highlight a bigger truth:
Organic doesn’t automatically mean free from contamination.
Brands That Impressed Me With Transparency & Clean Ingredients
After seeing the gaps in testing from big brands, I focused on companies that:
Use organic and regenerative farming
Provide real sourcing transparency
Use compostable, plastic-free tea bags
Have strong herbal or medicinal-grade standards
Support ethical supply chains
Don’t hide behind vague “proprietary blends”
Here are the ones that stood out:
Numi Tea (My #1 Choice)
Numi consistently ranks as one of the cleanest tea brands thanks to:
100% organic ingredients
Non-GMO
Compostable, plastic-free tea bags
Strong ethical sourcing
Transparent standards and ingredient integrity
If someone said, “Just tell me one safe brand to start with” — I’d say Numi.
Traditional Medicinals
This brand uses pharmacopoeial-grade herbs, meaning medicinal-quality — not just “good enough.”
They test for:
Identity (is the herb really what they say it is?)
Purity
Microbial contaminants
Heavy metals
Pesticides
Their testing standards go far beyond what food brands are required to do. This is one of my most used and trusted brands.
Pukka Herbs
Pukka is fully certified organic and Fair for Life, with an emphasis on regenerative farming.
They are known for:
Strict organic standards
Ethical sourcing
High-quality herbal blends
Sustainability focus
I personally wish they published more detailed contaminants testing, but overall they are a strong, trustworthy option.
Tahmina (Saffron Tea)
A smaller brand with:
Organic whole-leaf teas
Ethically sourced Afghan saffron
Plastic-free packaging
Clear, transparent information about suppliers
Small specialty brands like this often outperform bigger companies in integrity.
Saffron is also an adaptogen which helps with stress management.
Equal Exchange
A worker-owned co-op that focuses on:
Organic ingredients
Fair Trade
Farmer-led cooperatives
Soil health
Environmental stewardship
Their mission aligns beautifully with a cleaner, more conscious tea industry.
How to Choose Safe Tea (Even If Your Favorite Brand Isn’t on the List)
Here’s the checklist I now use:
✔ Look for real organic certifications
(Not just “natural” or “made with organic ingredients.”)
✔ Choose loose leaf when possible
No bags = no microplastics.
✔ Avoid “silky” pyramid bags
Many are made of PLA or nylon and shed particles in boiling water.
✔ Check if the company publishes any independent testing
If not, that doesn’t mean bad — but transparency matters.
✔ Avoid blends with vague “natural flavors”
Often a loophole for additives.
✔ Prioritize brands that talk openly about sourcing, soil health, and contaminants
✔ If in doubt, email them
Ask for a COA (Certificate of Analysis) for pesticides and heavy metals.
Any reputable brand will respond openly.
What I Personally Drink Now
These are the teas in my home that I trust and feel good about drinking:
Numi (my everyday teas)
Traditional Medicinals (for herbal and wellness blends)
Pukka (for cozy, flavorful blends)
Tahmina (for a luxurious, high-vibration cup)
Equal Exchange (ethically sourced and organic)
I don’t panic about tea.
I just make more conscious choices now.
And honestly, it feels empowering to know the story behind what I’m drinking.
Final Thoughts — Conscious Cups, Conscious Living
The goal of this post is not to create fear.
It’s to create awareness.
A lot of these issues aren’t malicious.
They’re symptoms of:
industrial farming,
supply chain complexity,
lack of transparency,
and contamination that can happen even under “organic” standards.
But when we know better, we choose better.
If tea is part of your rituals — your grounding, your healing, your cozy winter nights — you deserve for that ritual to nourish you rather than expose you to things you didn’t ask for.
And rebuilding your tea drawer with intention feels surprisingly magical.
