What is Iron (Loha / लोह)?

Loha (Iron) is the most commonly used metal in Ayurvedic medicine. Three types are described: Munda, Tikshna, and Kanta Loha. Kanta Loha (magnetite iron) is considered the best. Loha Bhasma is the chief remedy for Pandu (anemia), Kamala (jaundice), Yakrit-Pliha Roga (liver-spleen disorders), Shotha (edema), and Prameha (diabetes). It is Rasayana and enhances strength, complexion, and vitality. Iron must be properly purified by quenching in various liquids (Nirvapa Shodhana) and then incinerated through Puta method. Improperly prepared Loha Bhasma can cause constipation, acidity, and liver damage. Verses: 25-35.

Iron – Ayurvedic Healing Properties

Iron is beneficial for bone marrow, bone tissue, red blood cells, liver and spleen. It increases the production of red blood cells and therefore the ash is used to treat anemia. It is effectively used as an antidote for enlargement of the liver or spleen. Iron strengthens muscle and nerve tissues and has rejuvenating properties.
