The product information lists chaga mushroom, ginger root and rosehip as the key ingredients. These are herbal ingredients rather than black tea, green tea, mate or coffee. Based on that composition, this drink is suitable for people who are looking for a warm herbal infusion instead of a typical caffeinated beverage; however, always check the full label if you need to avoid caffeine strictly.
The best time to drink it depends on why you are choosing it. In the morning or during the day, it can be a warming alternative to regular tea or coffee. In cold weather, the ginger component may make it feel especially comforting. Rosehip and chaga add an antioxidant-focused profile, so it may also suit a routine where you prefer drinks with plant-based supportive ingredients rather than sweet soft drinks.
If you are sensitive to warming herbs, start with a milder infusion and see how it suits you. Because ginger can feel quite warming for some people, you may prefer not to drink a very strong cup right before bed. For regular daily use, keep the preparation moderate and combine it with a balanced diet and enough water throughout the day.
