Specific Properties of Shilajeet:

Chedana : is one which expels the kaphadi doshas from the Srotas with the force due to Prabhava of the drug. Chedana drugs are usually belonging to amla, katu rasa and teekshna guna.

1. Amla helps in vilayana of obstructive materials.
2. Katu & Tikta expel the vitiated material form the Srotas with the above diathesis the obstructive kapha and other material have been cleared out from the Srotas. Due to above properties Shilajeet acts as chedana.

Anulomana: Gives strength to the intestinal structures and releases the vata from the intestines. Triphala shodhita Shilajeet possess ushna virya and anulomana properties.

Balya : The drug which increases vitality is called balya.
Medhya: The drug that is capable of increasing intelligence is called as medhya. There is no rigid rule that medhya drug should possess madhura rasa and sheeta virya. Even ushna virya and tikta rasa drugs can act as medhya. So it is due to Prabhava of the drug that Shilajeet though ushna in virya and tikta in rasa, still increases grahana shakti (grasping power) or smarana shakti (memory power).

Hridya : ushna virya, katu rasa gives stimulation to the heart function. Cardiaotonic are drugs which improves the action of heart by increasing the tone and nutrition of the cardiac muscle where as cardiac stimulants are used as an emergency measure to tide over a critical period. Cardiaotonic produces a more permanent effect. These may act either directly on the muscle, possibly by giving rest i.e. increasing the period of diastole and improving nutrition through better coronary circulation or indirectly by improving the general health and condition of blood.

Deepana: The drug which stimulates the gastric fire is called deepana. Shilajeet is having the properties of katu, ushna virya and laghu guna so it acts deepana. Vagus nerve is having some control over the secretion of the HCl and pepsin. Katu rasa of Shilajeet stimulate the function of the Vagus. So the normalised function of the stomach also help in digestion. Even from the modern idea also bitters aromets are good stimulants.

Pachana: The drug that disintegrates ama but does not stimulate agni, is called Pachana. Shilajeet owing to katu tikta rasa, ushna virya helps in pachana of ama.

Rasayana : Is one which increases the rasa raktadi dhatus. Also it increases the longevity, resistance, power and imparts rejuvenation to the body is called Rasayana.
