Problem: East Tucson is relatively new compared to other parts of the city, developed between the 1950s and the 1970s,[citation needed] with developments such as Desert Palms Park. It is generally classified as the area of the city east of Swan Road, with above-average real estate values relative to the rest of the city. The area includes urban and suburban development near the Rincon Mountains. East Tucson includes Saguaro National Park East. Tucson's "Restaurant Row" is also located on the east side, along with a significant corporate and financial presence. Restaurant Row is sandwiched by three of Tucson's storied Neighborhoods: Harold Bell Wright Estates, named after the famous author's ranch which occupied some of that area prior to the depression; the Tucson Country Club (the third to bear the name Tucson Country Club), and the Dorado Country Club. Tucson's largest office building is 5151 East Broadway in east Tucson, completed in 1975. The first phases of Williams Centre, a mixed-use, master-planned development on Broadway near Craycroft Road, were opened in 1987. Park Place, a recently renovated shopping center, is also located along Broadway (west of Wilmot Road).

The Charaka Samhita, thought to have been written between 300 and 500 AD, mentions a metal which, when oxidized, produces pushpanjan, thought to be zinc oxide. Zinc mines at Zawar, near Udaipur in India, have been active since the Mauryan period. The smelting of metallic zinc here, however, appears to have begun around the 12th century AD. One estimate is that this location produced an estimated million tonnes of metallic zinc and zinc oxide from the 12th to 16th centuries. Another estimate gives a total production of 60,000 tonnes of metallic zinc over this period. The Rasaratna Samuccaya, written in approximately the 13th century AD, mentions two types of zinc-containing ores: one used for metal extraction and another used for medicinal purposes.
What are the two uses of zinc ore mentioned in the Rasaratna Samuccaya?
A:
metal extraction and another used for medicinal purposes
