I had the same problem with my tomatoes and common sage, it got rectified, you can use an organic insecticide in dilute form to tackle the problem.

I used neem oil solution with water. Caution: I had used a larger concentration earlier which led drying of my leaves, which is similar to what you got. After diluting the concentration, and spraying it 2-3 times with an interval of 2-3 days, the problem got fixed.

I also massaged the area a bit to manually remove the aphids

Hope it helps
