When you are pregnant or breastfeeding, it can feel very restrictive with food and drink. Sitting down with a warm, comforting mug of herbal tea feels like the ultimate restorative ritual. However, because herbs contain active, plant-derived pharmacological compounds, navigating commercial “mama” or “wellness” blends can feel daunting.
Not every herb that is natural is automatically benign. Some botanical compounds easily cross the placental barrier or pass into breast milk, while others can influence maternal hormones or impact milk supply.
To bring clear clinical discernment without the internet noise, we turn to e-lactancia.org a gold-standard, peer-reviewed database maintained by APILAM (Association for Promotion of and Cultural and Scientific Research into Breastfeeding) that classifies substances by evidence-based risk levels.
Here is a clear breakdown of which herbal teas offer gentle, safe support, and which ones should be avoided.
| Herbal Tea | Botanical Name | e-lactancia Risk Level | Status | Maternal Benefits & Clinical Notes |
|---|---|---|---|---|
| Ginger | Zingiber officinale | Very Low Risk (Compatible) | Safe | Well-researched for easing first-trimester nausea and gastric sluggishness. Postpartum, it supports digestive warming and comfort. Stick to standard culinary steeped root or bagged teas. |
| Rooibos (Red Bush) | Aspalathus linearis | Very Low Risk (Compatible) | Safe | Naturally 100% caffeine-free and low in tannins (which can otherwise inhibit maternal iron absorption). Packed with cellular antioxidants like aspalathin, making it an ideal evening swap for black tea. |
| Chamomile | Matricaria chamomilla | Very Low Risk (Compatible in moderation) | Safe (Culinary strength) |
Soothes the nervous system, supports restorative sleep, and eases digestion. Stick to standard culinary German chamomile (1–2 steeped cups daily). Avoid therapeutic extracts or high-dose Roman chamomile. |
| Spearmint | Mentha spicata | Very Low Risk (Compatible) | Safe (Culinary strength) |
A gentler alternative to peppermint with naturally lower menthol levels, making it less likely to affect milk supply. Soothes pregnancy nausea, indigestion, and bloating. Stick to moderate culinary infusion amounts (1–2 cups daily) and avoid concentrated essential oils. |
A Note on Preparation: “Culinary” vs. “Therapeutic”
When an herb is designated as Very Low Risk, that rating applies strictly to culinary-strength infusions, meaning a standard tea bag or a modest slice of fresh root steeped in boiling water for 3 to 5 minutes, enjoyed 1 to 2 times a day.
It does not apply to:
- Concentrated liquid extracts or herbal tinctures.
- Essential oils added to drinks (which should never be ingested).
- High-dose herbal supplement capsules.
How to Check Your Own Teas
If you have a loose-leaf blend or a commercial tea at home with multiple ingredients, check each component individually on e-lactancia.org. You can search by common English names or the botanical Latin name listed on the back of the packet.
If you are ever uncertain about a specific blend, you can also consult The Breastfeeding Network Drugs in Breastmilk Information Service alongside your GP or midwife.
