Taiwan Buddhist group sends low-fluorine tea to Tibet

Taipei – A Taiwan Buddhist group, believing the high- fluorine milk tea which Tibetans have been drinking for centuries is bad for their health, is sending low-fluorine tea to Tibet, the group said Tuesday. The Buddhist Tzuchi Foundation joined Chinese researchers in studying the tea-drinking habits of Tibetans in 2000 and since 2004, has distributed 144 tons of low-fluorine tea to Tibet, the group’s deputy leader Wang Tuan-cheng said.

For thousands of years, Tibetans have been drinking milk tea to help them digest meat and stay warm in the harsh climate. Tibetan soil has a high fluorine content, which is absorbed by the tea bushes.

Chinese scholars noticed the high levels of fluorine in Tibetan milk tea in 1983 and launched a field study in 1994.

Tzuchi listed fluorine poisoning by tea as one of its overseas relief projects in 2000.

In 2004, Tzuchi and Chinese scholars launched a joint research project which discovered fluorine poisoning from milk tea among minority ethnic groups in Inner Mongolia, Tibet, Sichuan, Qinghai, Gansu and Xinjiang.

According to Tzuchi’s study, Tibetans drink large amounts of milk tea, sometimes up to 40-50 cups a day.

“They drink it like water, so it causes many health problems, like dental or skeletal fluorosis, yellow teeth, teeth decay and the stooping of the back,” Tzuchi’s Wang said.

According to the World Health Organization, a safe fluorine intake is 2 milligrams for a child and 4mg for an adult, but the fluorine in a kettle of milk tea (2,600 cubic centimetres from 100 grams of tea) made from the traditional Tibetan brick of tea is 6-10mg.

The fluorine content in the low-fluorine tea brick is less than 4mg.

Professor Cao Xing from China’s Central South University, who headed the research, has obtained the patent for the low-fluorine tea brick and wants to share it with Tzuchi.

But Tzuchi hopes Cao can pass the patent to China’s health authorities so that they can mass-produce low-fluorine tea bricks for Tibetans and other Chinese ethnic minorities.
