Osadhī
Osadhī,(f.) [Vedic avaṣa + dhī:bearer of balm,comfort,refreshment].There is no difference in meaning between osadha and osadhī; both mean equally any medicine,whether of herbs or other ingredients.Cp.e.g.A.IV,100 (bījagāma-bhūtagāmā ..osadhi-tiṇavanappatayo) Pv.II,610,with Sn.296 (gāvo ...yāsu jāyanti osadhā); D.I,12,cp.DA.I,98; Pv III,53; PvA.86; J.IV,31; VI,331 (? trsln. medicinal herb).Figuratively,“balm of salvation” (amatosadha) Miln.247.Osadhi-tārakā,star of healing.The only thing we know about this star is its white brilliance,S.I,65; It.20 = A.V,62; Vv 92; Pv.II,110; cp.PvA.71; Vism.412.Childers calls it Venus,but gives no evidence; other translators render it “morning star” .According to Hindu mythology the lord of medicine is the moon (oṣadhīśa),not any particular star.(Page 171)
