“…Homeopathy has been used in epidemics, but results are mostly historically described [35] , and data were not rigorously tested [36] . In the current COVID-19 pandemic, observational studies have been carried out with homeopathic preparations, such as Arsenicum album , Bryonia alba , Gelsemium sempervirens , Belladonna , Aconitum napellus , Eupatorium perfoliatum , Wyethia helenioides , Pulsatilla nigricans , Nux vomica , Rhus toxicodendron , complex Bryonia alba-China officinalis-Metallum album , Phosphorus , Sulphur , and China officinalis [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] .
