About a thousand years ago in present-day Afghanistan, the Islamic scholar al-Bīrūnī described tea and pot in his Book of Pharmacy. Some of al-Bīrūnī’s notes on tea:
- tea (chai) is a Chinese word for a herb drunk with hot water
- tea grows at high altitudes in China and Nepal
- the Chinese desiccate tea leaves and store them in a cube-shaped container; they also make tea tablets
- white tea is the most excellent variety of tea, but also difficult to find; varieties of tea, from the rarest to the most commonly available, are white, green, violet, grey, and black teas
- tea is important medicine: tea purges bile through the gastrointestinal system (a cholagogue), negates effects of liquor, purifies the blood, and abates fevers [1]
Al-Bīrūnī also preserved a traveler’s description of the economy of tea and pot in China:
the king of China resides in the city of Yanjū. A big river like the Tigris traverses through this city. Both sides of the river are studded with wine sellers’ tenements, kilns, and shops. People flock there to drink tea, and do not take Indian cannabis clandestinely. The king of the place receives the capitation tax, and the public cannot transact the sale of tea, since both tea and wine are the possession of the king. He who transacts business in salt and tea without the king being aware of it is awarded the punishment due to a thief. And the people there slay the thief and eat his flesh. Profits from such places go to the coffers of the king and such profits equal those accruing from gold and silver mines. [2]
This text probably describes the major Chinese city Yangzhou, which is on the banks of the Yangtze River.[3] Arab and Persian merchants were living in Yangzhou in the eighth century. That the Chinese king earned high revenue by controlling trade in tea, wine, and salt is probable. That’s particularly probable for tea because it was a popular, attractive product: people flocked to Yangzhou to drink tea.
What about the observation that people “do not take Indian cannabis clandestinely”? A variety of cannabis (pot), called Cannabis indica, is native to India. Cannabis has been consumed in India for thousands of years. Cannabis use in India, however, seems to have been associated with sacred festivals. Al-Bīrūnī’s description suggests that, unlike in India, pot in China was consumed popularly like tea.

Notes:
[1] Based on trans. Ahmad & Said (1973) pp. 105-6.
[2] Id. p. 105. The Chinese drank a wine made from rice. An Arab travel account from about 850 preserves a similar description:
The {Chinese} Emperor also reserves to himself the revenues which arise from the salt mines, and from a certain herb which they drink with hot water, and of which great quantities are sold in all the cities, to the amount of great sums. They call it Sah (Chah / Chai), and it is a shrub more bushy than the pomegranate-tree, but it has a kind of bitterness with it. Their way is to boil water, which they pour upon this leaf, and this drink cures all sort of diseases. Whatever sums are lodged in the Treasury arise from the poll tax, and the duties upon salt and upon this leaf.
Trans. Renaudot (1733) p. 25 (capitalization modernized). In the mid-eighth century, the Chinese writer Lu Yu wrote a monograph on tea, The Classic of Tea. That work also suggests that tea was highly popular in China.
[3] Another possible location is Guangzhou, which is on the banks of the Pearl River. Arab and Persian merchants also resided in Guangzhou in the eighth century. However, the reference to Yanjū seems phonetically closer to Yangzhou.
