Researchers tested 12 essential oils (EOs) to find ones that can block SARS-CoV-2 delta variant entry into cells without harming them. The EOs were tested on human angiotensin-converting enzyme 2 (HeLa ACE-2) cells using a pseudoviral entry assay and the XTT assay. Seven EOs, including Syzygium aromaticum, Cymbopogon citratus, Citrus limon, Pelargonium graveolens, Origanum vulgare, "Illicium verum", and Matricaria recutita showed promise in inhibiting the virus with potentially no harm to cells. The research suggests these EOs may be an alternative treatment for SARS-CoV-2 delta variant.
Researchers investigated whether feeding APP/PS-1 mice (a model for Alzheimer’s disease) raspberries could ameliorate microvascular pathology and improve cognition. Mice were fed glucose (control group), or glucose and red/yellow raspberries for 24 weeks and assessed post-intervention. However, long-term feeding of raspberries had limited effects on microvascular architecture or cognition, although there were changes in cerebral and plasmatic metabolites.
