Preparation method:
It is a soft mass of the herbs prepared by pounding them using mortar and pestle. If the herb is fresh and soft, it can be pounded and made into paste easily. If the herb part is dry like dried bark, then it has to be soaked in water for a few hours to allow it to absorb water and make it soft. Then the moist herb part is grounded in a mortar and pestle to obtain fine paste.

द्रव्यमार्द्रं शिलापिष्टं शुष्कं वा सजलं भवेत् ।
प्रक्षेप आवाप कल्कास्ते तन्मानं कर्षसम्मितम् ॥  Sharangdhara Samhita Madhyama Khanda 5/1

Mukha Lepa

Acharya Charaka has explained that the prepared form of the medicine should be in bolus form.

य: पिण्डो रसपिष्टानां स कल्क: परिकीर्तित : ॥  Charaka Samhita Sutrasthana 4/7

The bolus form explains about the consistency of the final product i.e it should be neither too liquid nor too dry. If the prepared kalka is prepared properly with exact water content, only then it can be rolled into a bolus form. Care should be taken that any fibrous part present in the herb should be removed during the preparation of the kalka, so that the bolus form can be properly obtained.

In the ancient books of Ayurveda like Charaka Samhita, Sushruta Samhita and Astanga Sangraha, the term kalka was used for the paste which could be used both for internal use and external use as application.

Dosage and shelf life

The dosage of kalka is said to be 1 karsha (about 12g) and it has to be consumed immediately after the preparation.
For external usage of the kalka, quantity sufficient was used depending upon the area to be applied.

Prakshepaka Dravyas

Prakshepaka dravya (Adjuvants):
कल्के मधु घृतं तैलं देयं द्विगुणमात्रया ।
सितगुडं समं दद्यात् द्रवा देया: चतुर्गुणा: ॥   Sharangdhara samhita Madhyama Khanda 5/2 

The adjuvants used along with the kalka which are used, for the internal uses are as follows:
Madhu- Honey
Ghrita- Ghee
Taila- Oil

These are added double the quantity of kalka during consumption.
Sita- Sugar candy
Guda- Jaggery

These are added equal to the quantity of kalka during consumption.
Drava- Any liquid as per the reference.

It is added four times to that of kalka during consumption.

लेपात् निम्बदलै: कल्को व्रणशोधनरोपण:।
भक्षणात् च्छर्दि कुष्ठानि पित्तश्लेष्म कृमीञ्जयेत् ॥ Sharangdhara Samhita Madhyama Khanda 5/7

Lepa Ayurvedic therapy

The leaves of nimba (Azadirachta indica) is crushed in a mortar and pestle and made into a paste. This paste is used both internally and externally. Internally it is used along with sesame oil to treat intestinal worms, skin diseases and vomiting. Externally this kalka is applied over infected wounds to treat it.


As told earlier, in the ancient Ayurvedic classics there was no separate preparation told for external usage. Kalka was the term used for the preparation which was used both for external and internal use. But later on, in books like Sharangadhara Samhita, Bhava Prakasha, the term ‘Lepa’ was used for the preparation which was exclusively used for skin application.

Preparation, types

Method of preparation:
The preparation of lepa is similar to kalka. One or more herbs are taken in fresh form and grounded to paste form. If the part of the plant is dry, small amount of liquid like water, milk can be added and grounded to paste form. The words Lipta, Lepana have been used as synonyms to Lepa.

द्रव्यमार्द्रम् शिलापिष्टं शुष्कं वा सद्रवम् तनु ।
देहे प्रलेपनार्थं तल्लेप इत्युच्यते बुधै: ॥Yadavji.

Rules and regulations

 Rules and regulations to be followed during the application of the lepa.

  • All the lepa prepared are for instant and single use.
  • Lepa is applied against the direction of the hair follicles for better absorption.
  • Lepa is removed soon after drying from the skin.

  • Lepa should not be applied during night time except in conditions like poisonous bites, pus filled wounds. The lepa which is applied during the night time prevents the exchange of body heat with the atmosphere.

Purpose of lepa

Lepa was formulated with the intention of localized action of the herb. The thickness of various types of lepa is told to enable the active principles present in the particular lepa to be absorbed into the skin and do the desired action when the lepa is in wet condition and before it dries. In some of the diseases, along with lepa, internal medications are also needed.
