Help !! Anyone know what this is ?

My kitten's (Calli) losing patches of hair and it looks like this. My mom applied some traditional medicine on her and said we should wait a few days before going to the vet but I'm so worried.. Calli has no appetite and isn't zooming around like crazy anymore, which is odd because she would chase me around the house ! Now she's sitting under a table or under a chair all alone..
