Herbalists are reporting a surge in demand for herbal products, particularly winter teas like sage tea and linden, as the weather starts to cool down. These products are sought after by citizens looking to boost their immune system and protect themselves from colds and flu. Mehmet Yıldız, a trader at the Eminönü Spice Bazaar, mentioned that sage tea is sold for 80 liras per kilo, and linden for 300 liras. Customers usually purchase 100-150 grams of these herbal teas.
