Abstract

Background: The metal Nāga (Lead) is being used by Indians since ancient times. Its external and internal uses have been described in Caraka, Suśruta and other Ayurvedic Saṃhitā. According to most of the Rasa texts, Nāga Bhasma and its formulations are used in many diseases such as Prameha, Jvara, Gulma, Śukrameha etc.

Objectives: In the present study, Nāga Bhasma was prepared by the traditional Puṭa method (TPM) and by the electric muffle furnace Puṭa method (EMFPM) and standardized using Metallographic studies. Doing so helps in the study of the microstructure of Nāga Bhasma and also helps in the identification of the metal particles along with the nature of compound formed during the Māraṇa (Bhasmīkaraṇa) process.

Setting and design: Different samples from initial raw material to final product of Nāga Bhasma were collected during the pharmaceutical process (1st, 30th and 60thPuṭa) from both methods i.e. TPM and EMFPM. Samples from both methods were studied using metallographic examination.

Materials and methods: The processing of the Nāga Bhasma (ṣaṣṭipuṭa) was done according to Ānanda Kanda[9] Samples from the raw material i.e. Aśodhita Nāga (raw Lead) and that processed after 1st, 30th and 60th Puṭa from both methods i.e. traditional Puṭa method (using heat from burning of cow dung cakes) and electric muffle furnace Puṭa method were taken. They were mounted on self hardening acrylic base. After careful polishing to obtain scratch free surface of product, they were used for metallurgical study.

Conclusion: This study shows that traditional Puṭa method may be better than electric muffle furnace Puṭa method because of more homogeneous distribution of Lead sulphide in the Nāga Bhasma which is prepared by traditional method.

Nāga Bhasma的冶金研究。
背景:金属Nāga(铅)自古以来就被印度人使用。在卡拉卡,Suśruta和其他阿育吠陀Saṃhitā中描述了它的外部和内部用途。根据大多数Rasa文本,Nāga Bhasma及其配方用于许多疾病,如Prameha, Jvara, Gulma, Śukrameha等。目的:在本研究中,Nāga Bhasma采用传统的Puṭa方法(TPM)和电马弗炉Puṭa方法(EMFPM)制备,并采用金相研究进行标准化。这样做有助于研究Nāga Bhasma的微观结构,也有助于识别金属颗粒以及Māraṇa (Bhasmīkaraṇa)过程中形成的化合物的性质。设定与设计:在制药过程中(1日、30日和60thPuṭa),采用TPM和EMFPM两种方法,从初始原料到最终产品Nāga Bhasma收集不同的样品。用金相检验对两种方法的样品进行了研究。材料和方法:根据Ānanda Kanda[9]对Nāga Bhasma (ṣaṣṭipuṭa)进行加工,样品取自原材料Aśodhita Nāga(生铅)和1日、30日和60日Puṭa之后加工的样品,分别采用传统Puṭa法(利用牛粪饼燃烧产生的热量)和电马弗炉Puṭa法。它们被安装在自硬化丙烯酸基上。经过仔细的抛光,使产品表面无划痕,用于冶金研究。结论:由于传统方法制备的Nāga Bhasma中硫化铅的分布更为均匀,因此传统Puṭa方法可能优于电马弗炉Puṭa方法。
