Dandelion leaf salad, dandelion leaf tea, and dandelion leaf extract in pill forms are all good ways of getting the spike protein-fighting substances of dandelion leaf into your system. Remember not to use dandelion leaves from chemically-treated lawns however!
University of Freiburg, Germany: Common dandelion (Taraxacum officinale) efficiently blocks the interaction between ACE2 cell surface receptor and SARS-CoV-2 spike protein
"Here we report on the efficacy of common dandelion (Taraxacum officinale) to block protein- protein interaction of spike S1 to the human ACE2 cell surface receptor. This could be shown for the original spike D614, but also for its mutant forms (D614G, N501Y, and mix of K417N, E484K, N501Y) in human HEK293-hACE2 kidney and A549-hACE2-TMPRSS2 lung cells…
"The common dandelion (Taraxacum officinale) belongs to the plant family Asteraceae, subfamily Cichorioideae with many varieties and microspecies. It is a perennial herb, native distributed in the warmer temperate zones of the Northern Hemisphere inhabiting fields, roadsides and ruderal sites. T. officinale is consumed as vegetable food, but also employed in European phytotherapy to treat disorders from the liver, gallbladder, digestive tract or rheumatic diseases. Modern herbal monographs consider the plant usage as safe and have evaluated the empiric use of T. officinale with a positive outcome.
Therapeutic indications for the use of T. officinale are listed in the German Commission E, the European Scientific Cooperative for Phytotherapy (ESCOP) monographs (11, 12) as well as in the British Herbal Medicine Association (13). The plant contains a wide array of phytochemicals including terpenes (sesquiterpene lactones such as taraxinic acid and triterpenes), phenolic compounds (phenolic acids, flavonoids, and coumarins) and also polysaccharides (14). The predominant phenolic compound was found to be chicoric acid (dicaffeoyltartaric acid). The other were mono- and dicaffeoylquinic acids, tartaric acid derivatives, flavone and flavonol glycosides.
The roots, in addition to these compound classes, contain high amounts of inulin (15). Dosage forms include aqueous decoction and infusion, expressed juice of fresh plant, hydroalcoholic tincture as well as coated tablets from dried extracts applied as monopreparations (16) but also integral components of pharmaceutical remedies. Our research was conducted using water-based extracts from plant leaves. We found that leaf extracts efficiently blocked spike protein or its mutant forms to the ACE2 receptor, used in either pre- or post-incubation, and that high molecular weight compounds account for this effect…"
