Tisane vs. infusion
In French, tisane and infusion are often used interchangeably to translate "herbal tea," but they technically refer to different aspects of the beverage. Tisane is the name of the final drink, usually consumed for health or relaxation, while infusion is the specific method used to prepare it.
Tisane
A2This word refers strictly to the beverage itself, distinct from tea (which contains theine/caffeine). A tisane is traditionally associated with medicinal properties, digestion, or sleep aid, and implies a blend of dried herbs, flowers, or spices.
Je bois toujours une tisane à la camomille avant de dormir.
(I always drink a chamomile herbal tea before sleeping.)
Cette tisane aide à soulager les maux de ventre.
(This herbal tea helps relieve stomach aches.)
Ma grand-mère connaît une excellente recette de tisane.
(My grandmother knows an excellent herbal tea recipe.)
Vous désirez du café, du thé ou une tisane ?
(Would you like coffee, tea, or an herbal tea?)
Infusion
B1Technically, this word describes the method of steeping plants in hot water to extract flavor. However, used as a noun for a drink, infusion sounds more elegant, modern, or culinary than tisane and is often found on restaurant menus or posh packaging.
Laissez l'infusion reposer pendant cinq à dix minutes.
(Let the infusion steep for five to ten minutes.)

(The chef offers a cold mint and lemon infusion.)
L'infusion permet de libérer les arômes des plantes.
(Infusion allows the aromas of the plants to be released.)

(I bought a box of red fruit infusion.)
Summary
To summarize, use tisane when discussing the traditional, comforting herbal drink often linked to well-being or home remedies. Use infusion when discussing the brewing process (steeping), or when you want to make the drink sound more sophisticated and trendy, particularly with fruit or gourmet blends. Technically, you make a tisane by performing an infusion.
