Star anise is widely known for its antiviral effects in Chinese medicine. It is also the source of the precursor molecule, shikimic acid, which is used in the manufacture of oseltamivir (Tamiflu®), an antiviral medication for influenza.
Contrary to what you may have heard, covid is a vascular disease, not a respiratory disease. This explains the wide range of symptoms as the so-called spike protein antigen replicates and causes the blood to clot in capillaries and vessels all over the body. (See article: https://www.holistichealthonline.info/pfizer-shedding-spike-proteins/) The ACE-2 (angiotensin converting enzyme-2) receptor protein has been identified as the region of viral entry. This protein is found on cells of the upper and lower respiratory tract, heart and vasculature, kidneys, and gastrointestinal tract.
When the spike protein binds to the ACE2 receptor on cells, it diminishes the function of the mitochondria (energy storage units) of those cells, causing damage to lung tissue, heart cells, blood vessels, etc.
To keep it simple, there are 3 things in general to know about spike proteins: 1) they are toxins, 2) they are what creates the problems in those who get the covid disease, and 3) they are what the mRNA vaccines (genetic manipulation experiment) contain, and also encourage the body to make more of when inoculated.
Shikimic acid is known to halt blood clotting ability depending on dose. You can make your own extract and tea, and drink as you like. Watch Mike Adams below. Pine Needle Tea is another good source of shikimic acid. See recipe here: https://www.holistichealthonline.info/pine-needle-tea-shikimate-antidote-spike-protein/
