As this has popped up, I'll add that my father's mother's family were herbalists, midwives, nurses and similar, and when my legs and feet were dangerously swollen after having the first AZ jab, plus being rather ill, I used ginkgo biloba, an extract of the maidenhair tree, and a circulation booster after antibiotics did not resolve the painful and discoloured toe problem. Thankfully in 24 hours there was a noticeable improvement. the end joint of the toe most affected is fused now, but otherwise it seems all is well.
Not every herbal remedy is a fraud, as some were used to good effect for many centuries and are now made or even improved on by modern science. Asprin is one which comes to mind - extract of willow bark.

Indeed. Also Metformin and digoxin are two I use with significant effect.
Here is food for thought for any budding apothecaries.

Another source is WebMD which also gives quite sound reviews on supplements.
