Synoptic Review on Aṣṭāngavaleha- A Polyherbal Ayurvedic Formulation for Bronchial Asthma
Introduction: Avaleha (Linctus) is a unique dosage form of Ayurveda that is frequently used in various disorders and as Rasāyana (Immunomodulators). Aṣṭāngavaleha is one such formulation being used for Śvāsa (Asthma), Jvara (Fever), Hikkā (Hiccup) and Kāsa (Cough). Aṣṭāngavaleha has not been mentioned in Brūhattrayī. It had been extensively reviewed from Vrndamādhava, Cakradatta, Vangasena, Ġadanigraha, Śārangadharasaṁhitā, Bhāvaprakāśa and Yogaratnākara. Screening through various texts revealed that Aṣṭāngavaleha has been mentioned in these treatises with few modifications like changes in Anupāna (vehicle) or few ingredients. Methods: An attempt has been made to compile scattered information about Aṣṭāngavaleha from the texts of 9th to 20th AD explaining its pharmacological potential in Śvāsa along with the pharmacological activities of its ingredients from Brūhattrayī and Nighaṇṭus. Results: Among these texts, Aṣṭāngavaleha had been mentioned by different name in four texts, with different Anupāna (adjuvant) in one text, its use for different disease in two texts, mentioned with different ingredients in two texts and with different preparation method and Anupāna in Ayurvedic Pharmacoepoeia of India. Conclusion: This work may prove a torch bearer for future research works on Aṣṭāngavaleha.
