In brief: Kasisadi Thailam (also written Kasisadi Taila, Kasisadi Thailam, Kasisadi Tel or Kasisadi oil) is a classical Ayurvedic oil for the skin, named after Kasisa, the mineral that leads its recipe, cooked with plant ingredients into sesame oil. It is cited from the Sharangadhara Samhita and is one of the few classical oils built around a mineral rather than a plant. It is applied to one small area, in small amounts, on the advice of a practitioner. This guide covers the name, the classical description, how an oil of this kind is applied, who should ask first, and which Art of Vedas oil comes closest.
What Kasisadi Thailam is and what the name means
Kasisadi is a compound of two parts. Kasisa is the Sanskrit name of a mineral, the green iron sulphate that the old texts also call green vitriol, and the ending adi means "and the others": the oil of Kasisa and the ingredients that follow it. Nearly every other Thailam is named after a plant. Kasisadi Thailam, Kasisadi Taila, Kasisadi Thailam, Kasisadi oil and Kasisadi Tel all name the same preparation.
The classical description
The Sharangadhara Samhita is the source most often cited for Kasisadi Thailam. The classical recipe names Kasisa first, followed by plant ingredients that share its sharp character; no full list and no count is given here. In the Sneha Paka method the ground ingredients are cooked slowly into sesame oil until the water has gone. Our complete guide to traditional Thailams explains the method.
Minerals are used in Ayurveda only after a preparatory processing the texts call Shodhana, and a classical Kasisadi Thailam is made with Kasisa that has been through it. That is one more reason to use an oil of this kind only on the advice of a practitioner.
Character in Ayurvedic terms
The classical texts describe Kasisa as warming and sharp and place it with Kapha and Vata; Kasisadi Thailam is described in the same terms, a Tikshna oil, sharp and penetrating, the opposite of the soft, nourishing oils of the daily routine. The tradition therefore uses it on a small area, in small amounts and for a limited time, never for whole-body Abhyanga.
How a classical skin oil of this kind is used in practice
Kasisadi Thailam is applied to one small area of the skin. Wash and dry the area first, take a small amount on a clean cotton swab or a fingertip and apply a thin layer to the area only, without spreading it onto the surrounding skin. Leave it on for the time the practitioner sets, then wash the area with warm water and wash the hands. No warming is needed.
Because the oil is sharp, a first application is kept very small so that the skin can be watched. The rhythm, once or twice a day for a short period, is set and reviewed by the practitioner; it is not an oil to continue for weeks without a check. Use a fresh swab each time and close the bottle straight after use. Our Abhyanga guide describes the whole-body routine, a different practice.
Who should ask first
Kasisadi Thailam is a classical oil to be used on the advice of a qualified Ayurvedic practitioner. It is for external use only. Do a small skin test on the inner forearm before the first application, keep the oil away from the eyes, the mouth and the inside of the body, and do not apply it to broken skin unless a practitioner directs it. If you are pregnant, or wish to use any oil on a child, ask your doctor or a qualified Ayurvedic practitioner first. Anyone who reacts to sesame should not use it.
Kasisadi Thailam, Jathyadi Thailam and the Art of Vedas range
Jathyadi Thailam is the classical skin oil people most often look at alongside Kasisadi. Both are sesame-based oils for one area, applied in a thin layer with a clean swab. Jathyadi Thailam is led by Jati, the jasmine leaf, and described as soothing, the oil the tradition reaches for first; Kasisadi Thailam is led by a mineral and described as sharp, the stronger, shorter-term oil a practitioner chooses on purpose.
Art of Vedas does not currently offer Kasisadi Thailam. The closest oil in our range is Jathyadi Thailam, not a substitute for a Kasisa oil but the nearest in kind. For the gentler everyday oils, see our comparison of Ayurvedic massage oils.
