20.51

又僧祇十誦五分律等。更無餘治。開病比丘服蒜。聽七日在一邊小房內。不得臥僧床褥。眾大小便處。講堂處皆不得到。又不得受請及僧中食。不得就佛禮拜。得在下風處遙禮。七日滿已澡浴熏衣。方得入眾。若有患瘡。醫教須香治者。佛令先供養佛已。然後許塗身。還在屏處。一同前法（出家性潔尚令作法如是況穢俗凡夫輒開食耶）。

Also, the Mahāsāṃghika, Sarvāstivāda, and Mahīśāsaka Vinayas and others state: If there is no other cure, an exception allows a sick bhikṣu to take garlic. He is permitted for seven days to stay in a small room on one side. He must not lie on the bedding or mattresses of the Saṅgha, nor may he go to the places where the assembly relieves nature or to the lecture hall. Furthermore, he may not accept invitations or eat amidst the Saṅgha, nor may he approach the Buddha to pay homage; he is permitted to pay homage from afar downwind. When seven days have been fulfilled and he has bathed and perfumed his robes, only then may he enter the assembly. If one suffers from sores and the physician instructs that fragrant medicine is required for treatment, the Buddha instructed that one must first make offerings to the Buddha, and only then is it permitted to smear it on the body, remaining in a secluded place, just as in the previous procedure. (If the renunciant nature of purity still requires such procedures, how much less may foul, common worldlings casually indulge in eating them?)
