Khon Kaen University has launched a throat spray containing Fah Talai Jon (green chiretta) to inhibit the spread of Covid-19 in the mouth and throat.

Assoc Prof Dr Chanchai Panthongwiriyakul, the university rector, and Nopparat Inwiset, the lead researcher at Miss Lilly Co, Ltd unveiled the product based on the joint research of the academic institute and company at a press conference yesterday.

Dr Chanchai said the active ingredient of green chiretta -- Andrographolide -- has a preventative and treatment effect against Covid-19 and can inhibit the coronavirus.

Until now, the plant has been processed in the form of pills and capsules, each containing 1.38-3.21% of the substance.

The substance is non-water soluble, so the human body can absorb 2.67% of its weight. People need to take four capsules at a time, four times a day to reach the prescribed dose of 6,000 milligrammes containing 60mg of Andrographolide.

Researchers then used nano-emulsion to enhance its absorbing capacity and maximise its effect.

Dr Chanchai said the plan is to distribute the medicine in 10mg and 20mg bottles next month. Some have already been sold at Srinagarind Hospital at the university's Faculty of Medicine, and drug stores run by the university.

The spray supports the government's roadmap of easing measures on July 1, he said.
