Dosage & Administration
|The general dosage of Naga Bhasma is as follows:-|
|Children||2 mg per Kg body weight *|
|Adults||125 mg *|
|Maximum possible dosage||500 mg per day in divided doses|
|* Twice daily with honey, butter or milk cream|
|Note: However, 125 mg is recommended dosage, but there is no need to use it in larger doses in many cases. Its reduced dosage of 20 to 25 mg twice daily also works well. Larger dose does not increase its effect in several diseases especially in severe constipation, impotency, rheumatoid arthritis etc. But its continuous use for 3 to 4 weeks in smaller dose is more beneficial.|
|As, it is dubious regarding the effects of lead content in the body and safety profile is also not well established, so one should not consume it more than 4 weeks on daily basis in its recommended dosage. We should try to avoid it when other better alternatives are available.|
The study for toxicological effect was conducted on albino rats in which 6 mg /100 g body weight/day dose is given to the rats. The study found that there were no histopathological changes observed in skin, kidneys, brain, testes, liver, lungs, and small intestine of the rats. (Reference)
Still the safety profile is not well established for its long-term use in human.
Clinically, there are no observable side effects found with Naga Bhasma when used for less than 4 weeks, but it may have adverse effects when used for a longer duration.
However, we are not sure about the side effects due to its lead content. According to lead content level, its long-term use may result in kidney damage and other symptoms of chronic lead poisoning.
