Use of Complementary and Alternative Medicine (CAM) and Home Remedies by COVID-19 Patients: A Telephonic Survey

COVID-19 is caused by a novel coronavirus which was first reported in Wuhan city, China. The pandemic has led to considerable mortality globally. India, at present has the second largest burden of COVID-19 cases globally. Clinical trials with new interventions, including new vaccine candidates are being explored in the scientific world. Countries like China and India, with a rich history of traditional medicine, are exploring the effectiveness of traditional medicines to treat COVID-19. This study included 725 patients from an Isolation center, of which 230 (31.7%) were excluded due to reasons like incorrect phone numbers, no response on phone, or denying consent to participate. Finally, 495 participants had responded, of which 367 (74.1%) had not used any Complementary and Alternative Medicine (CAM) product or home remedies while 128 (25.8%) people used 161 CAM products and home remedies during the treatment and even afterward. More than half of the participants (59.6%) among them had consumed Ayurvedic Kadha. Many respondents consumed more than one CAM products or home remedies but there were no reported acute or severe adverse effects with these products. However, it is essential to ensure the safety of these interventions on long-term use because patients with other comorbidities can have a detrimental effect due to these products or due to drug herb interaction with their ongoing medications. Hence, long-term follow-up studies of recovered patients are crucial in determining the effects of medications or CAM products on organ functions due to disease or interventions.
