In Ayurvedic practice, the classification and properties of lavana (salt) are crucial for dietary and therapeutic purposes. While modern science views salt largely as a single compound, sodium chloride, Ayurveda details five distinct types known as Panchalavana. These are differentiated by their source, processing, chemical composition, and specific effects on the body's constitution, or doshas. The most esteemed among them is Saindhava lavana for its balanced properties. Understanding these distinctions allows for a more tailored and holistic approach to using salt for health.
Saindhava Lavana: The Best of All Salts
Saindhava lavana, or rock salt, is widely regarded in Ayurveda as the superior salt for consumption. It is a naturally occurring mineral form of sodium chloride, often found as large crystals in regions like the Himalayan mountains. Unlike other salts, it is considered to have a cooling effect, or sheeta virya, which makes it suitable for all three doshas (Vata, Pitta, and Kapha). Its key properties include being light, unctuous, and sharp, with therapeutic uses for digestion, appetite, eye health, and the heart. It is particularly known for calming Vata.
Samudra Lavana: The Common Sea Salt
Samudra lavana, or sea salt, is obtained from the evaporation of seawater. Ayurveda notes its heavier, more unctuous nature compared to rock salt. Its properties can increase Kapha dosha if consumed in excess. It is described as slightly heavy and unctuous, with therapeutic uses as a laxative and aid for digesting vegetables.
Sauvarchala Lavana: Aromatic Black Salt
Also known as Kala Namak, Sauvarchala lavana is a black salt recognized for its distinctive sulfuric odor and flavor. It can be naturally occurring or artificially prepared. This lavana is light, subtle, and has a heating potency. It is an anti-flatulent, relieves constipation, and is used for abdominal bloating and indigestion.
Vida Lavana: The Penetrative Salt
Vida lavana is another type of black salt, prepared artificially. Its defining feature is its penetrative, or vyavayi, quality. This lavana is sharp, hot, and light. It is known for pacifying Vata dosha, aiding in the downward movement of gas, and addressing indigestion and abdominal pain.
Romaka Lavana: The Earthen Salt
Romaka lavana, also called Sambhar salt or earthen salt, is naturally harvested from saline lakes. It is sometimes equated with Audbhida lavana. Its properties include being very hot in potency, sharp, and light. It improves digestion strength, is laxative, and is useful for constipation and low appetite.

The Ayurvedic Perspective on Lavana
In Ayurveda, lavana is a therapeutic substance with the power to both heal and harm, depending on its type and usage. While it stimulates digestion and enhances taste, it can also aggravate Pitta dosha. Saindhava lavana is considered the most balanced due to its cooling effect. The principles of Panchalavana highlight the importance of a substance's origin and processing, as seen in the distinct properties of Sauvarchala and Samudra. Ayurvedic practitioners select the right salt for specific health conditions, such as using warming salts like Vida or Sauvarchala for Vata-related constipation, or the cooling Saindhava for a Pitta imbalance.
Conclusion
Understanding what are the five types of lavana provides a deeper appreciation for Ayurveda's sophisticated approach to diet and medicine. Beyond the simple, modern table salt, these five salts—Saindhava, Samudra, Sauvarchala, Vida, and Romaka—offer a spectrum of therapeutic benefits rooted in their unique properties and origins. By choosing the right type of lavana for individual needs, one can harness its full potential for improving digestion, balancing doshas, and promoting overall wellness, all while honoring a tradition that has valued this crucial mineral for millennia.
