owshadham= medicine owlookam = owl
Hey! Isn't that funny? 
Owlookam in Malayalam means Owl in English! 
There are many such similar instances in Malayalam.

For eg: 
Kayar in Malayalam is coir in English
Cashumanga is Cashew
Thek is Teak
These are few of the words that have been absorbed from Malayalam into English. Malayalam has also borrowed freely from English and that has resulted in there being no real Malayalam equivalents for words like switch, bench etc!
