FWIW, osha is a weed growing in the American SW. Those with wildcrafting skills interested in herbalism could collect their own. Then again, those in the SW have the climate that tends to inhibit the spread in the first place.
Oscillococcinum active ingredient is duck hearts and livers. Those that are interested in this substance that also have a palate that allows such things might just make a habit of giblet based suppers until this blows over.
Good info thank you. This is what’s needed.
