An actual question I got:

Is it safe to take Portulaca for my parents who did this week the vaccination of corona?

Of course it should be safe [like any other vegetable] but I will not advise to do so. Why not? Only for legal reasons [for myself]

If G-d forbid any serious reaction develops then of course Pfizer and all health authorities will may suggest that this was a “side-effect” of the vegetable Portulaca……because the vaccine is “totally safe: we are living in a bit of an insane world.
