THERE IS no disease against which turmeric has not been tested,” says G Padmanaban, former director of Indian Institute of Science, Bengaluru. The spice used in households across the subcontinent is the only natural source of curcumin—the compound that gives turmeric its golden hue and its fabled healing qualities. Turmeric (Curcuma longa), native to India, has been studied extensively for its effects against viral diseases in recent decades, but the covid-19 pandemic has renewed interest in the spice and in curcumin, both of which have been tested as a treatment for the viral disease, with encouraging results. Sample these:
In a covid-19 hospital in Maharashtra, patients who received a combination of 525 mg of curcumin and 2.5 mg of piperine (naturally occurring complex organic molecules containing nitrogen) twice a day, recovered faster from symptoms such as fever, cough, sore throat, and breathlessness. They were able to maintain oxygen saturation above 94 per cent on ambient air, and had better clinical outcomes compared to control group members who received a probiotic instead. The treatment also reduced the duration of hospitalisation and resulted in fewer deaths, researchers report in the journal Frontiers in Pharmacology published on May 28, 2021. In another study, researchers in Iran observed the efficacy of curcumin in the form of nanoparticles on 21 patients. The results showed that most of the common symptoms of covid-19 resolved significantly faster in the curcumin group. The treatment group did not need as much oxygen supplementation and had reduced stays in the hospital compared to the control group. Patients in the treatment group did not experience deterioration of infection during the follow-up period, while 40 per cent of the control group did, the researchers report in the journal Phytotherapy Research on January 3, 2021.

WATER SCARREDCITY
Bengaluru's water crisis was long in the making. The city has grown at the cost of its lakes and ponds that are key to its water security. Over 93 per cent of the city is built-up, which makes groundwater recharge difficult. Inadequate sewage systems pollute the limited water available. Over the decades, the city has become dependent on the Cauvery, 100 km away, for 70 per cent of its water needs. This makes water unaffordable. It's time Bengaluru broadened its water resource base beyond the Cauvery and focused on recharging groundwater and reusing treated wastewater.
