The word "kharsivan" is a Persian term that refers to a type of medicinal herb. It is pronounced as /xær.siːˈvɑːn/ in IPA phonetic transcription, which breaks down as follows: the "kh" at the beginning represents a voiceless velar fricative sound, while the "a" in the middle is pronounced as a short vowel. The "r" is rolled, and the "s" sounds like a voiceless alveolar sibilant. Finally, the "i" and "v" are both pronounced as short vowels, and the final "an" ending is pronounced as a nasal vowel.
Trade name of an English made substitute for salvarsan, used in the same manner and dosage as the latter.
