Development of standard manufacturing process of Tryushanadya Lauha – An organo-metalic preparation

Abstract

Tryushanadya Lauha (TL) is one of the herbo-mineral formulations in many Ayurvedic texts. Tryushanadya Lauha consists Loha Bhasma and Tryushana, which includes Pippali (Piper longum Linn), Maricha (Piper nigrum Linn), and Shunti (Zingiber officinale Roscoe), Cavya (Piper chaba Hunter), Citraka (Plumbago zeylanica Linn),  Bakuchi (Psoralea Corylifolia Linn), and  Lavana (salt), which includes Saindhava (Sodium chloride), Aubhida (sodium carbonate), Vida (Ammonium chloride), and Sauvarchala (Sodium sulphate). This study is an effort to develop the standard operating process for manufacturing of Loha Bhasma and Tryushanadya Lauha. As per the reference of Rasatarangini, Loha Bhasma (incinerated ash of iron) was prepared in three batches. The processing of Loha Bhasma (ash of iron) was performed by adopting, Shodhana (purification), a special heating process and Marana (incineration). For the process of Levigation decoction of Triphala was used. Puta (heating process) was given in Electric Muffle Furnace at a temperature of 500 ⁰C. The percentage of loss was 49.9% after purification. During Loha Bhasma (incinerated ash of iron) preparation 14.7%loss and 85.3% gain were observed. This Loha Bhasma was used for the preparation of TL. During TL preparation, 0.6% loss was observed & 99.3% was obtained. This study will give the direction for the standard manufacturing process of Loha Bhasma (incinerated ash of iron) and Tryushanadya Lauha.
