Q. (See question 2618 above – regarding a person that is prone to seizures). I also started eating cloves ie tziporen because has been B’H helping me with stopping the seizures from starting. Can I get a heter for that too?
Can one use cloves for besamin on havdalah during Pesach? 
A. Rema (O.H. 467: 8) mentions that it is tradition in his country not to consume “neglach” or cloves , Mishna Berura (24) explains that they would wash them with mei seorim or barley water, Sidur Pesach Kehilchoso (16: 3, p.336), Shulchan Aruch Harav, Shemiras Hamoadim (p.246) and others maintain that the minhag is to abstain from them. Chometz Mashehu (p. 102) opines that it can be consumed with a hechsher, since it is not common to be washed these days with barley water.
Horav Shlomo Miller’s Shlit’a opinion is that you can certainly eat cloves if it has a good effect on you.
The Rov also maintains they can be used as besamim for havdalah.
