Some herbal medicines include a soothing ingredient (4)
I believe the answer is:
balm
'a soothing ingredient' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'some herbal medicines include' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'BALM' is hidden in the letters of 'herbal medicines include'.
Can you help me to learn more?
(Other definitions for balm that I've seen before include "It comforts, soothes" , "There's comfort" , "Unguent" , "Royal holiday residence on the River Dee" , "Something soothing" .)
