That’s how we gain knowledge about the depths of Ayurveda and why it is called the science of life. The gems of Ayurveda include herbs, minerals and many herbo mineral combinations also. Some peculiar mineral combinations are also there. Even certain metals are also used when it comes to preparation of formulations and these metals are only used after purification. This article is about one such metal formulation called loh or simply iron. The article has information about loh bhasma which is the calx of iron and its uses along with benefits.

The text also explains how the bhasma is to be prepared and how firstly how the purification of the iron is to be done. Loh bhasma is also mentioned for some really specific conditions in the Ayurvedic texts and its use even in small quantities gives very great and effective results. Loh bhasma helps in reducing the general weakness due to its balya or strengthening properties and also has Vrishya or aphrodisiac effect. Moving further in the article we will discuss all about loh bhasma, its uses and its indications. This article also covers the importance of metal based formulation in Ayurveda.

Starting With All About Loha Or Iron

After the systematic knowledge of gold, silver and copper the population of earth came to know about iron. Due to extensive use of iron the present age is termed as The age of iron as well. The Indians especially, are in touch with the uses and benefits of loha or iron from quite a time. Even in ancient Indian texts, the references of Iron can be seen very often. In India, iron is not only used for weapon making but also for many purposes related to our day to day life like utensils etc. In this the knowledge to have fine varieties of iron was also established. From Ancient history it is very clear that India has extensive ores of Iron and this iron was even transported to many parts for the world so that production of weapons can be done.

Even many of the top scientists of the world have no answers on how the Iron pillar of Delhi stands rust free after standing tall in an open environment, how the iron doors of somnath temple still appears almost new, why the big iron pillars in jagannath temple still stand without any damage and many more examples like that. The examples explain the knowledge and creativity of Indian ironsmiths at that time.

Though the medicinal knowledge of Iron came into limelight a bit later. In the middle of the time of acharya charak the loh or iron was used in the form of power, calx, tablets, varti that is a type of suppository and aasav aarisht. At the time of acharya Sushruta the preparation of iron calx was done in a more significant way. But when it was the era of rasashastra that was the time when the actual use of iron in Ayurvedic and Unani medicine started.

Facts About Iron Or Loha

  • Iron is a brownish coloured lustrous metal
  • It is affected by environmental factors, presence of oxygen and water due to which it catches rust.

In these three kant loha or magnetic iron ore is the best one. Further, the kant loha is divided into three types that is bhramak kantloha, chunbak kantloha, karshak kantloha, daravak kantloha abd romkant kantloha.

Facts About Loh Bhasma

Loh bhasma is prepared using the kant loha. Kant loha is tested using various methods to find out whether it is finest or not. In rasashastra that is one of the medicinal branches of Ayurveda, following pariksha are suggested to test its quality:

  • The oil poured in the kant loha utensil will not spread
  • When hing paste (Asafoetida) is applied over the kant loh utensil, the smell of hinga will disappear.
  • If water is boiled in the kant loha utensil then it will smell like Hing (Asafoetida).

All three can be performed and if the utensil passes then it is the finest type of  Kant loha which is Such easy ways, no doubt Ayurveda science has many hidden gems..!!
