Thank you Redskies for your constructive criticism and the link. It is good to have people such as yourself on the forum with such knowledge i must admit my knowledge on wild plants is limited but now i understand the risks of the Foxglove. I did not advise its use i simply put it forward and quantified it with (much research needed before use) perhaps i need to curtail my imagination. You were the only person who addressed the risks in an intelligent manner with-out demeaning my ignorance so once again i say thank you.
I'm always happy to help out as much as I can with herbs etc. Knowledge weighs nothing, and should be freely shared, because only then does it have value
Sorry I've been missing for a while due to family pressures.
The back story on foxgloves and the heart is fascinating. A local wise woman in Shropshire described treating "dropsy" and a chap William Withering ( http://en.wikipedia.org/wiki/William_Withering ) realised that foxglove ( http://en.wikipedia.org/wiki/Digitalis ) was the key ingredient. What made his work special is he spent a lot of time working out that the strength of the medicine extracted varied widely and he worked out how to test the toxicity and strength. IIRC he used to test how much was needed to kill a frog!
The drug digoxin is the active ingredient. Medically it is now only really used for certain types of rapid heart beat ( mainly atrial fibrillation known to health workers as AF - http://en.wikipedia.org/wiki/Atrial_fibrillation ). In theory is is a way to treat AF but it is a difficult drug to use even today so it is falling out of use. You would have to be pretty desperate to use it as a foxglove extract.
