Herb Tea Man is a story-driven adventure simulator set in the 1990s in Guangdong, Hong Kong, and Macau. You play as Sun, a man from Northern China who works in a traditional herbal tea shop, brewing medicinal infusions, serving customers, and solving local problems related to traditional Chinese medicine concepts like inner heat and excess moisture. The game combines simple control mechanics with environmental puzzles: you learn about authentic medicinal herbs chrysanthemum, honeysuckle, and licorice root and select them according to your customers' symptoms. Four mischievous spirits, representing Moisture, Heat, Cold, and Toxins, will help you gradually uncover your master's mysterious past.
