Why This Matters
The tea industry has a massive plastic problem that most consumers are completely unaware of. When you drop a conventional tea bag into boiling water, the heat breaks down the thermoplastic sealants used to hold the bag together. Do Tea Bags Have Microplastics
A landmark McGill University study found that a single plastic tea bag releases 11.6 billion microplastics and 3.1 billion nanoplastics into a single cup. Drinking tea shouldn't mean drinking a credit card's worth of plastic particles. Are Tea Bags Safe
Contamination doesn't stop at the packaging, as tea leaves are notoriously high in pesticide residue. Because tea leaves are never washed before they are dried and steeped, any chemical sprayed on the crop goes directly into your mug. Pesticides In Tea
Conventional teas are also notorious for heavy metal contamination from polluted soil. Older tea leaves bioaccumulate lead and fluoride, making third-party testing for heavy metals absolutely essential. Heavy Metals In Tea
What's Actually In Numi Tea
Numi takes a purist approach to its formulations, relying entirely on real plant materials.
- Organic Full-Leaf Tea — Numi uses higher-quality, whole tea leaves rather than the cheap "tea dust" that makes conventional teas taste bitter. What Should You Look For When Buying Tea
- Real Fruits and Spices — The brand uses actual dried bergamot, real jasmine blossoms, and organic cocoa husks instead of lab-made flavor sprays.
- Unbleached Manila Hemp — Their tea bags are made from abaca (a type of banana plant fiber) and are completely plastic-free and biodegradable. What Tea Bags Are Plastic Free
- Soy-Based Inks — Even the ink on the tea tags is non-toxic, and the string is made from 100% natural organic cotton.
What to Look For
Green Flags:
- Plastic-free packaging — Look for unbleached hemp, abaca, or organic cotton instead of nylon, PET, or polypropylene. Plastic Free Tea Bags
- USDA Certified Organic — This certification guarantees the tea was grown without synthetic pesticides or fertilizers. Does Organic Tea Have Less Pesticides
- Real botanical ingredients — Safe teas use actual herbs and spices to build their flavor profile.
Red Flags:
- "Natural flavors" — This regulatory loophole allows companies to hide up to 100 synthetic chemical solvents and preservatives in a single ingredient.
- Silky pyramid bags — Those fancy, translucent pyramid bags are almost always made of PET plastic or nylon, which aggressively leach under high heat.
- Epichlorohydrin — This is a carcinogenic chemical often added to conventional paper tea bags to keep them from disintegrating in boiling water.
