Tea and the effects of tea drinking

by W. Scott Tebb

Eight grammes of each sample were weighed out and were then infused in a tea-pot for five minutes with 600 cubic centimetres of boiling distilled water. At the end of five minutes the infusion was poured off and analysed for the percentage of extract, alkaloid, and tannin, and the following tables show figures for the Indian, Ceylon and China teas respectively.
