A natural remedy for tonsillitis

So this little patient is my friend's son. Sunday - Tuesday this week he was very poorly. He has a history of tonsillitis and antibiotics. Since having Homeopathic constitutional treatment he has avoided antibiotics. On Tuesday his Mum contacted me with his symptoms.
High temperature
Throat "On fire"
"So thirsty"
Breath smells
I ask her to give him 3 doses of Merc viv daily over the next couple of days.
Today she tells me "Merc viv worked like a miracle"
Here he is today at Forest school
