Herbal teas, also known as herbal infusions or tisanes, are a popular drink made from various parts of plants such as leaves, flowers, branches, and roots. Different parts of the plant are used depending on the desired effect, with ginger root being a common ingredient in the Philippines known as salabat. The tradition of drinking tea for health benefits dates back centuries, with Queen Catherine and Charles II introducing tea to England and the Tang dynasty in China popularizing compressed teas. As a result of trade, tea spread to the Middle East, Europe, and eventually the Americas. Different countries have created their own variations of herbal tea, such as Sri Lanka's Afternoon Tea and Thailand's Herbal Tea. Traditional Japanese tea ceremonies, known as Chadô, are also centered around herbal tea. In southern Chinese cities, there are specialized shops called "herbal tea shops" that sell a variety of herbal teas.
