Daurian Rhododendron Oil — Classic Formulas
Man Shan Hong You · Oleum Rhododendri Daurici
Primary Actions
- Stops cough and transforms phlegm - Man Shan Hong You is the concentrated volatile-oil preparation made from Man Shan Hong leaves and is used for productive cough with bronchial irritation.
- Benefits acute and chronic bronchitis - modern Chinese materia medica and pharmacopoeial use centers on bronchitic cough rather than on broad general herbal indications.
- Opens constrained Lung Qi - the penetrating aromatic oil is used when sticky phlegm and cough obstruction are difficult to clear with milder preparations.
Classic Formulas
- Man Shan Hong You capsules or pills - the standard finished-product form for acute and chronic bronchitic cough.
- Man Shan Hong You derived from steam-distilled leaf preparations - a preparation-based respiratory approach rather than a broad classical decoction tradition.
- Adjunct use with the crude Man Shan Hong leaf tradition - the oil preparation preserves the same cough-phlegm treatment direction in more concentrated form.
Classical Text References
- Chinese pharmacopoeial usage describes Man Shan Hong You as the volatile oil obtained by steam distillation of Rhododendron dauricum leaves and used for cough and expectoration.
- The preparation is aimed mainly at acute and chronic bronchitis rather than at the wider folk indications sometimes attached to the leaf herb itself.
- PREPARATION NOTE: this file intentionally distinguishes the oil from herb #303 because the distilled oil is a separate medicinal product with a narrower respiratory focus.
