Some fun facts about the herb:
The common English name for this herb is Groundsel. According to Collins English Dictionary the name origin is from Old English gund pus and swelgan to swallow or absorb. In olden days before the discovery of antiseptics and antibiotics a poultice made from the herb was apparently effective for treating suppurating wounds.
It is also called ragwort because its leaves look like torn cloth(rags).
The origin of its botanical name has been described in "A Modern Herbal" by Mrs.M.Grieve in the following words "Senecio, derived from Senex (an old man), in reference to its downy head of seeds; 'the flower of this herb hath white hair and when the wind bloweth it away, then it appeareth like a bald-headed man.". The English word "Senile" has the same origin.
