INTRODUCTION

Ayurveda
Ayurveda can be defined as a system, which uses the inherent principles of nature to help maintain health in a person by keeping the individual’s body, mind and spirit in perfect equilibrium with nature.

Ayurveda is a Sanskrit term made up of two words ‘ayu’ and ‘veda’. ‘Ayu’ means life and ‘veda’ means knowledge. The term ‘Ayurveda’ thus means ‘knowledge of life’. According to ancient Ayurveda scholar Charaka, ‘ayu’ comprises the mind, body, senses and soul.

Ayurveda is an intricate medical system that originated in India thousands of years ago. The main aim of this system is to protect illness, heal the sick and preserve life. The fundamentals of Ayurveda can be found in Vedas, the ancient Indian books of wisdom.

Agadatantra
Agadatantra is one of the eight branches of Ayurveda which explains about visha along with its properties, action, fatal dose, detection, symptoms shown by intake of visha and its treatment measures.

The word ‘agadatantra’ is derived from the combination of two words, Agada and Tantra. Agada means the medicaments which are used as an anti dot to combat the morbid condition. Tantra means science through which the positive health of an individual is preserved.

As regards origin of visha, Lord Shiva describes the visha as a result of the churning of the milk ocean by devas and daityas using the serpant king Vasuki as the rope of churning.

Lead poisoning
Lead poisoning (also known as plumbism, colicapictonium, saturnism, Devon colic, or painter’s colic) is a medical condition caused by increased levels of the heavy metal lead in the body.
Lead is a ubiquitous metal that has been used by humans for more than 3 millennia. Its toxic effect on humans is well documented in history. As with other metals, the soluble compounds of lead are more poisonous than lead itself, except when lead is in the volatile state. Lead may obtain access to the body by inhalation, by ingestion or by absorption from the skin or mucous surface. The primary effect of lead is to cause spasm of the capillaries and arterioles. The toxic effects results from fixation of lead in certain tissues such as the brain and peripheral nervous system.

LEAD
Lead is one of the first metal known to man, the references of which are abundantly available in vedic literature also. It is the commonest metal involved in chronic poisoning. It has been widely used during the last 2000 years for domestic, industrial and therapeutic purposes. It is distributed throughout the earth crust. It is abundant in soil and is poison in both metallic form and salts. Physical appearance: It is heavy, soft, and steel-grey. Salts are variously coloured.

PREPARATIONS OF LEAD
Lead Acetate-Pb(C2H3O2)2.3 H2O
Lead acetate is commonly called sugar of lead or salt of Saturn. It occurs in white masses of acicular crystals, slightly efflorescent and having a sweet, astringent taste. It dissolves in water, forming an acid solution. It is also soluble in glycerine and alcohol (90%). It looks very much like loaf sugar. It was used to sweeten wine in old days. Lead Subacetate-Pb2O(C2H3O2)2

Lead Subacetate is the chief constituent of Gouldard’s extract(liquor...
