can you identify this very mysterious plant?

When I was a child, an elderly relative was given this very unusual pot plant but no one ever knew its name or where to find it.

It is an indoors pot plant with a large, overground bulb which produces small, 'pickled onion' type bulbs.

When these small bulbs are cut open, they produce a milky fluid very useful against the itch and swelling of insect bites, stinging nettles etc.

I never saw this plant again and wonder if anyone could help me identify it?

Many thanks

It's a mystery to me as well. The only plant that I know you can cut off the thick watery leaves to rub on skin conditions is 'Aloe vera' but that's a succulent plant not a bulb.

What did the plant look like?

Difficult to describe. Best to search for images under Aloe vera plant. Lots of clear pictures.http://www.google.co.uk/search?q=aloe+vera&hl=en&rlz=1W1GGLL_en&prmd=imvnsl&source=lnms&tbm=isch&sa=X&ei=K2P4T86UOciHhQeyjNm3Bg&ved=0CEYQ_AUoAQ&biw=1024&bih=563

I wonder if it was a Tree Onion?  The juice of onions has long been used for soothing itchy insect bites.

I didn't mean your plant Doris - I meant the mystery plant.
