In their August 2022 study, Strub and colleagues investigate the anti‑SARS‑CoV‑2 activity of 538 essential oils, aromatic extracts and F&F raw materials (natural flavors and fragrances).

Substances with a high monoterpene and monoterpenoid content have no or the lowest activity against the viruses that cause SARS (Severe Acute Respiratory Syndrome). Petitgrain mandarin (Citrus reticulata, steam distillation, leaf) steals the show, possibly due to its high concentration of dimethyl anthranilate (DMA).
