Astanga Hrudaya
वदन्त्यन्ये तु न दिवा प्रयोज्यं तीक्ष्णमञ्जनम्। विरेकदुर्बलं चक्षुरादित्यं प्राप्य सीदति॥१८॥
Others say, that strong Anjana should not be applied during day, because the eye which has become weak by purgation treatment from strong herbs will be further debilitated by the presence of the sun.
english translation
vadantyanye tu na divA prayojyaM tIkSNamaJjanam। virekadurbalaM cakSurAdityaM prApya sIdati॥18॥
