Like some remedies brother turned over, central to cure (6)
I believe the answer is:
herbal
'like some remedies' is the definition.
(as in herbal remedies)
'brother turned over central to cure' is the wordplay.
'brother' becomes 'br'.
'turned over' says the letters should be written in reverse.
'central to' indicates putting letters inside (letters are inserted into the centre of the word).
'cure' becomes 'heal' (synonyms).
'br' written backwards gives 'rb'.
'rb' put within 'heal' is 'HERBAL'.
(Other definitions for herbal that I've seen before include "Book describing the uses of plants" , "Relating to plants such as rosemary, thyme" , "Relating to plants such as sage and rosemary" , "Type of tea" , "like Basil?" .)
