Research on the production process of herbal tea bags from Indian insulin Plants (Costus pictus).

Result of herbal tea:

• The method of drying samples at -20^oC for 24 hours has been selected, freeze-dried at -50^oC and 0,125 mbar for the highest Diosgenin and Flavonoids content 16,36 µg/g and 2,27 mg/g.
• Selected the method of packaging with vacuum-sealed plastic bags to help preserve optimally.
• Tea steeping time for convenient use and optimal Diosgenin and Flavonoid content when steeping tea with boiling water for over 30 minutes.
• The production process of herbal tea bags has been built: leaf harvesting, cutting, drying, powdering, vacuum packing.
