I use them with iced tea. Two regular teabags and one herbal teabag to half gallon boiling water. Let stand for four minutes. Remove teabags and refrigerator. Also, one teabag in mug. Add boiling water. Let stand four minutes. Remove teabag. May sweeten. Soothing at night. Enjoy. Thank you.
The box says it's distributed by a company in New Jersey and is a product of Poland with selected herbs from other countries but there is no specific mention of China being one of those countries.
