甘菊茶 (gānjúchá): chamomile tea

甘 (sweet) + 菊 (chrysanthemum-family flower) + 茶 (tea). Chamomile (Matricaria chamomilla) belongs to the same family (Asteraceae) as the chrysanthemum, so calling it 'sweet chrysanthemum tea' is botanically reasonable as well as descriptive of the taste.

culture

甘菊茶 is associated in Chinese marketing with European herbal-tea culture — calming, sleep-aiding, often sold in 花草茶 (huācǎochá, herbal flower tea) shops alongside 薰衣草 (lavender) and 玫瑰花茶 (rose tea).
