The effects of hyssop and mullein tea on the clinical symptoms of COVID-19 patients

The use of medicinal herbs as treatments for different illnesses has a long history. This research aims to study the effects of hyssop and mullein tea on the clinical symptoms of COVID-19 patients. This was a triple-blind clinical trial study performed on 80 COVID-19 patients hospitalized in Khomeini’s Imam Khomeini Hospital. The intervention group received 250 ccs of hyssop and mullein tea three times a day for eight days along with their normal treatment, while the witness group only received the normal treatment. All patients were monitored for coughing, dyspnea, hoarseness, sore throat, and body pain throughout the experiment. In the end, the Stata-17 statistical software was used to compare the five symptoms mentioned above among the patients.

There were no significant differences between the two groups in the five clinical symptoms (sore throat, body pain, dyspnea, cough, and hoarseness) before the intervention began. However, differences appeared after the intervention. After six days of intervention, the two groups were meaningfully different in the cases of all five clinical symptoms. Fewer patients in the intervention group reported these symptoms. Analyzing the effects of the intervention on clinical symptoms indicated that the patients in the intervention group had a significantly lower chance of experiencing the five symptoms. The use of hyssop and mullein tea as supplementary treatments can decrease clinical symptoms in COVID-19 patients and quicken recovery.
