Somehow trim and cure plant tied to 1ac vessel... (8)

I believe the answer is:

turmeric

I'm a little stuck... Click here to teach me more about this clue!

'plant tied to 1ac vessel' is the definition.
I can't tell whether this defines the answer.

'somehow trim and cure' is the wordplay.
'somehow' is an anagram indicator.
'and' says to put letters next to each other.
'trim'+'cure'='trimcure'
'trimcure' with letters rearranged gives 'TURMERIC'.

Can you help me to learn more?

(Other definitions for turmeric that I've seen before include "ginger relative" , "Powdered plant stem used as condiment" , "Yellow powder used in Indian cookery" , "A curry spice; cruet rim (anag.)" , "Bright yellow spice" .)

I've seen this clue in The Hindu.
