I've seen St John's wort mentioned a few times in this thread. FWIW it's part of our anti-spike protocol, now used as a add-on, when there's too many freshly jabbed (fresh is relative, could be 9 months to a year and they're still shedding) around my kids in school or on public transport. Our first line of defence is still the nicotine patch with Black Seed Oil, very convenient.... which works very well for the most part, but dosing has to be limited as there's much more singificant toxicity above certain levels. But there's no noted side effects with St John's wort... so the kids will surreptiously pop a couple of pills every few hours while in school to top up their anti-spike protection. Does the job of mopping up any stray spike that got through the other lines of defence.
