Miriam-Webster gives both "smooths" and "smoothes" as the 3rd person singular present form. I've always used the "e".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
You surprise me.
I've never seen smoothes before in my life.
It seems to be more popular in AmE than in BrE. COCA has 146 'smoothes' and 243 'smooths'. I must have been reading too much colonial literature.
I think it looks wrong without the "e." So there you go.

"Eating chicken soup to combat a cold is an age-old remedy, dating back to 12th Century physician Maimonides, and it may work. Drinking warm liquid soothes the nasal passages while the soup seems to act as an anti-inflammatory. Protein from chicken and antioxidants from vegetables also help the body make virus-killing antibodies."

Thank you all.
These posts were nothing to do with the original question on 'sweet/sweat', so I have moved them to a new thread.
