No way having strange medicine (7)
I believe the answer is:
nostrum
'medicine' is the definition.
(nostrum is a kind of medicine)
'no way having strange' is the wordplay.
'way' becomes 'st' (**).
'having' means one lot of letters go next to another.
'strange' becomes 'rum' (I've seen this before).
'no'+'st'+'rum'='NOSTRUM'
(Other definitions for nostrum that I've seen before include "Favourite remedy or scheme" , "Must Ron take a quack remedy?" , "Quack remedy or pet scheme" , "Some think it helps" , "our Latin" .)
