The plants are in pots and not POT!!!

I did some research and it looks like an aphid invasion. I don't know
from where they cropped up!!

Anyways... I did the following:
1. Cut all affected leaves and stems (mint will grow just the same)
2. Made a mixture of 1tbsp dish-washing liquid and 1 quart water and
sprayed on the mint.

I hope this solves the problem. Would the leaves still be edible?

Thanks,
Max
