BANGKOK, Jan 14 (TNA) – The Department of Medical Sciences has found Thai herbal fever medications can contain COVID-19 in test tubes.
Dr Supakit Sirilak, director-general of the department, said it studied the property of “Ha Rak” and “Prasa Proh Yai” herbal medications in containing the Delta variant of COVID-19.
The department initially found that water-based Ha Rak extract could control 96.23% of Delta at the concentration of 10 milligrams per milliliter. Water-based Prasa Proh Yai extract could control 76.56% of Delta at the concentration of 10mg/ml and Prasa Proh Yai extracted with 50% alcohol solution could stop 88.70% of Delta at the concentration of 2.5mg/ml.
Ha Rak and Prasa Proh Yai are in the Public Health Ministry’s list of herbal medicine for fever treatment. Their application for COVID-19 treatment should wait for officials concerned to conclude the study first, Dr Supakit said.
The department would speed up the study which covered pre-infection antibody stimulation, infection prevention and the safe use of the medicine, he said. (TNA)
