Is this the right place to ask specific grammar questions?
Please refer to this sentence:
日本では、処方箋のいらない頭痛薬が約15 種類もあります。
"In Japan, there are about 15 types of headache medicine that don't require a prescription."
What's the nuance of the も particle in that sentence? My guess is that it's the indication that the medicine is available, and ALSO doesn't require prescription.
