A tisane is a drink made of an infusion or decoction of spices, flowers or other plant material in hot water. Such drinks are also referred to as herbal teas. The plants, flowers or spices could be of various species except for the tea plant, Camellia sinensis, in which case the drink would be referred more simply as tea. Tisanes, unlike teas, typically do not contain caffeine.
A tisane is one of Poirot's favourite drinks and in Christie's stories, he might have a tisane at any time of the day. He believes they have medicinal benefits. The exact type of flower or leaf he prefers is not always stated but in The Adventure of the Egyptian Tomb he is served a tisane of camomile. But this may not be his usual as Hastings often describes his tisanes as "noxious".
Tisanes also feature prominently in adaptations as a way of depicting the Poirot's peculiarities.
