What is etymology for Horsetail ?

In Japan Spring has come. We can see many spring flowers here and there on the streets which are soil or along the river.

Recently I found a Horsetail near my house.

I would like to know etymology of horsetail.

Or should I say what is word origin for housetail

I would like to know why people call it horsetail because I can see there are two words “horse “and “tail “

Horsetail (scientific name -- Equisetum) is a poisonous plant, and when horses occasionally eat it, they get sick. Although it resembles a horse's tail, without that fact people probably didn't name it such.

If eaten over a long enough period of time, some species of horsetail can bepoisonous to grazing animals, includinghorses. The toxicity appears to be due to thiaminase enzymes, which can cause thiamine (vitamin B1) deficiency. This is a citation from wikipedia.

Do those people expose it to heating, or eat it fresh? Of course, I assume, that there is another Equisetum species in Japan, not poisonous.

Hi Hossein. Thank you for your comment.

I checked it ,  but a little bit difficult for me to get the definition. I would take horsetail means literally “ horse 's tail “ right ?

In Japan people sometimes eat horsetail.

So it means literally look like “horse's tail “
