Your Herbal Tea Questions, Answered

The honest answer is: it depends on the herb. Delicate flowers like chamomile and elderflower are at their best at five to six minutes — any longer and they begin to taste bitter and hay-like. Roots and barks, like ginger and cinnamon, benefit from longer steeping or even gentle simmering: eight to twelve minutes extracts their full warmth without the bitterness risk that flowers carry.

Leaves and seeds sit in between. Peppermint is pleasant at five to seven minutes. Fennel seeds do well at eight. As a general starting point: five to seven minutes for flowers and leaves, eight to twelve for roots, seeds and bark.

Our steeping time guide has a detailed cheat sheet by herb type, and the Herbal Brewing Timer handles the countdown automatically.

Bitterness in herbal tea almost always comes from one of three causes: water that is too hot, steeping too long, or using too much herb in a small volume of water.

Delicate flowers — chamomile, lavender, rose — are particularly sensitive to overheating. Boiling water (100°C) can extract harsh bitter compounds very quickly. Try brewing them at 90–95°C instead: water that has sat off the boil for a minute or two. A few degrees makes a meaningful difference.

If your steep time is already short and the water temperature is right but the tea is still bitter, try slightly less herb per cup. A modest reduction (say, from two teaspoons to one and a half) often transforms the flavour. Our Tea Brewing Calculator can dial in the right ratio for any herb and cup size.

Many herbal teas can be re-steeped, but not all perform equally on the second infusion. Roots and barks — ginger, licorice, cinnamon — have dense structures that release their compounds slowly, making them excellent candidates for a second and sometimes third steep. Simply add fresh hot water and steep for slightly longer than the first time.

Delicate flowers and fine-cut leaves give most of what they have in the first steep and tend to produce a thin, watery second infusion. Re-steeping chamomile, for instance, rarely rewards the effort. Peppermint lands somewhere in the middle — a second steep is thinner but still pleasant.

If you are keen on re-steeping, keep your spent herbs in the pot rather than discarding them immediately. Give them a second steep within an hour of the first for the best result.

A good starting point for most loose herbs is one heaped teaspoon (approximately 1–2 grams, depending on density) per 250ml of water. That proportion works well for leaves, flowers and light seeds. For roots, barks and dense seeds, a slightly larger quantity — closer to two teaspoons — often performs better.

The best calibration, though, is your own taste. If a brew feels thin and watery, use more herb next time. If it is bitter or overpowering, use less. Herbal brewing rewards small, iterative adjustments rather than trying to find a single universal rule.

A kitchen scale helps considerably if you brew the same herb regularly — once you find the weight that suits you, it is repeatable. Our Tea-to-Water Ratio Calculator does the maths for any pot or mug size.

Four things damage dried herbs: air, light, heat and moisture. The solution is straightforward: an airtight container (glass or metal with a tight lid), stored in a cool, dark cupboard away from the hob and kettle.

Avoid keeping herbs in clear glass jars on a sunny windowsill — attractive as that looks, light degrades the volatile oils responsible for aroma and flavour relatively quickly. Dark jars or opaque tins are preferable.

Most dried herbs stay pleasantly aromatic for 12 to 18 months stored well. The best freshness check is your nose: a strong, distinct aroma means the herb is still good. A weak, dusty or hay-like smell suggests it has faded and a replacement is worth considering. See our full herbal tea storage guide.

Yes, and it is one of the most enjoyable aspects of loose herb brewing. Most herbs blend pleasantly as long as you pay attention to intensity — pairing herbs with similar strength means neither will overwhelm the other.

A simple starting framework: one base herb (something mild and voluminous, like chamomile or rooibos), one flavour herb (something with character, like peppermint or ginger) and optionally one accent (something aromatic, like lavender or lemon peel). Use proportions of roughly 60%–30%–10% to start.

Taste as you go. Blend a small test amount first before committing to a larger jar. Our Herbal Blend Planner makes the process systematic and saves your successful combinations for next time.

For most people, moderate enjoyment of a variety of herbal teas is perfectly fine as part of a normal diet. The key word is variety — rotating across different herbs rather than drinking large quantities of any single one is generally the more sensible approach.

Some herbs deserve extra care in certain situations. If you are pregnant, nursing, on medication or managing a health condition, it is worth checking with a qualified professional before adding a new herb regularly to your routine. Not because herbal teas are inherently dangerous, but because some herbs in some situations interact with things in ways worth knowing about.
