Excerpt: "This was shown in vitro using human kidney (HEK293) and lung (A549) cells, overexpressing the ACE2 and ACE2/TMPRSS2 protein, respectively. Infection of the lung cells using SARS-CoV-2 pseudotyped lentivirus was efficiently prevented by the extract. "
I don’t have time to read it now but I will tomorrow. Wondering if it is the root or the aerial portion of dandelion, very different uses medicinally.
dandelion extracts from paper...
“Molecular weight fractionation from plant extracts Extracts from dried plant leaves were prepared by adding bidistilled water (5 ml) to plant material (500 mg each). The samples were incubated in the dark at room temperature (RT) for 60 min, followed by centrifugation at 16.000 g for 3 min. The supernatants were collected and membrane filtrated (0.45 μm), resulting in the extracts. Aliquots were freeze dried for 48h to determine their yield by weight. The extracts were then further separated in a high molecular weight (HMW) and low molecular weight (LMW) fraction, using a centrifugation tube with an insert containing a molecular weight cut-off filter (5 kDa, Sartorius Stedim Biotech, Goettingen, Germany). Each HMW fraction was purified by flushing with 20 ml of water, yielding the HMW fractions, as well as LMW. The fractions were freeze dried, their yield determined by weight and stored at -20°C until use.”
easy peasy
What a coincidence, I bought a big bunch of dandelion at the store a few days ago, and have had salad each day now. I grew up eating it every spring, fantastic with sliced hard boiled egg, bacon, thin sliced onion and some parmesan flakes and a homemade dressing.
