The humble cup of herbal tea is where most people's relationship with plants begins. It is one of the oldest forms of plant medicine on earth, and it is also one of the most forgiving. You do not need special equipment, years of experience, or a long list of ingredients. You need a plant, some hot water, and a little patience.

An infusion is the technical term for what most of us call herbal tea. The word matters, because not every preparation method works the same way for every plant. An infusion is specifically suited to the delicate parts of a plant, the leaves, flowers, and soft aerial growth, where the constituents you are after are close to the surface and release easily into hot water without needing much coaxing.

What Makes a Good Infusion

The best infusions start with good plant material. Whether you are using dried herbs from a trusted supplier or fresh leaves from your garden, quality at the start means quality in the cup. Dried herbs are generally more potent (by weight) than fresh, because the water content has been removed and what remains is concentrated. A good rule of thumb is to use roughly one teaspoon of dried herb (or one tablespoon of fresh) per cup of water.

Temperature matters more than most people realise. Boiling water is perfect for robust leaves and aromatic herbs like peppermint, lemon balm, or nettle. For more delicate flowers, like chamomile or rose petals, you want water that has just come off the boil and cooled for a minute or two. Too much heat can volatilise the aromatic compounds you are trying to capture, leaving you with a flat and slightly vegetal cup instead of a fragrant one.
