Yes, it is safe to consume. Through a series of foreign matter removal, microbial control, and third-party inspections, we have the confidence to ensure that every cup of tea delivered to you is safe and reliable. If you are concerned about fine dust particles during the processing, we recommend a brief steeping before consumption. The first brew contains many nutrients, and with each subsequent brewing, the amount extracted will decrease. As for pesticide residue, most pesticides used are liposoluble, which means they are hardly soluble in water. Products that pass inspections have residue levels far below safe intake levels, so you can use our products with peace of mind.
