Lá mọc đối, hẹp, mặt dưới có lông sao trắng xám; chùy hoa dày đầu cành gồm nhiều hoa ống nhỏ vàng nhạt. Dược liệu khô là nụ/cụm hoa, không phải toàn lá hay vỏ. Dễ nhầm với Buddleja khác hoặc hoa khô trộn; đối chiếu cấu trúc hoa, Latin và nguồn. Ảnh AI để ghi nhớ, không tự chẩn đoán bệnh mắt hay tìm cây ngoài rừng. Mi Meng Hua is the dried bud/inflorescence of Buddleja officinalis, not a general eye-care flower. The shrub’s opposite narrow leaves, gray-white star hairs, and pale-yellow tubular flowers help orient an observer; dried buds may retain hairs and a short stem. A bundle of fragments cannot prove species or pesticide history, and the AI image is only a study illustration. Traditional sources use eye-related language, but chemical and cell studies do not establish treatment of cataracts, glaucoma, infection, or conjunctivitis. Never put a decoction, powder, or nonsterile extract into the eye; sterile eye products and diagnosis are clinical matters. The profile does not invent a toxic pair or formula ratio because a reliable standard was not found. HKBU gives habitat and seasonal notes but no universal age until flowering; growing a shrub for several years does not make its flowers medicinal-grade. Record species, bud versus open inflorescence, harvest location, drying, and contamination controls. Sudden vision change, eye pain, light sensitivity, or injury needs prompt eye care. The “eye” language attached to Mi Meng Hua should trigger careful reading, not eye-drop experimentation. A dried flower product is not sterile, and dust or decoction can irritate or introduce infection when placed on the eye. The shrub’s gray-hairy buds and pale-yellow flowers support identification study, but a photo cannot rule out another Buddleja or pesticide residues. No standard pairing ratio was verified, so the page does not supply one. Record whether a source describes buds, open inflorescences, or an extract, and do not transfer lab antioxidant findings into a treatment claim. Eye pain or sudden vision change is a medical issue. Traditional eye-related terminology describes how a source categorized the herb; it is not an eye-care instruction. A dried botanical material is not sterile, and eye symptoms can need prompt diagnosis. This distinction should remain visible even when the flower image looks gentle or familiar.
