Get the MILFOIL mug.
The vaginal juices of a MILF. Especially in referance to using them for cooking. See also milf oil.
Some like their veggies pan fried in olive oil, but I prefere the taste of veggies fried in milfoil.

Get the milfoil mug.
A small plant, Achillea millefolium, that grows all over North America and Europe. Means "a thousand leaves" because its leaves are so finely divided.

It can be used as an herbal remedy for colds and infections, but it must not be confused with the poisonous ground hemlock plant.
Leroy: I picked this milfoil in the woods; I can make it into a hot tea for you.

Grandma: L'awd have mercy! That's freakin' hemlock! Throw the dang stuff out, 'fore we all croak!
