Ever heard of an Ayurvedic herb that works as an ornamental plant and a medicinal boon? That’s Vacha for you. Loosely translated, Vacha means to speak clearly. This makes sense as this ancient herb aids in boosting your memory, intelligence, and brings about a sense of focus and clarity.

The Vacha plant is one of the most aromatic herbs you’ll find and is commonly cultivated in marshy places in India and Burma. Like ginger, it also has rhizomes which are similar looking. Note that its taste can be bitter but its health benefits are just as potent. Vacha (Sanskrit name) is commonly known by other names such as Sweet Flag (English name), Acorus Calamus (Botanical name), and Vach/Dhoda Vach (Hindi name).  

“Your body is precious. It is our vehicle for awakening. Treat it with care.” – Buddha

Alternatively, you can mix equal quantities of Vacha and Pipali and store in a container. Take about a pinch of this mixture and inhale through your nose. You’ll notice that the headache disappears immediately.

Poor Memory

Vacha acts as a perfect memory-booster and works on enhancing your concentration and focus. Take a few pieces of Vacha and boil it in the milk for some time. Then, take out the soaked pieces and let it dry under sunlight so that you can make a powder out of it. Consume around 2 gm of this powder with milk, twice a day. You can add a little mishri/sugar to it if the taste is too strong for you.

Sore Throat 

Oftentimes, erratic weather changes can lead to a sudden onset of sore throat and infection. In this case, take Vacha root and keep sucking on it in your mouth. Note that the taste might be a bit bitter so be prepared mentally. That said, consuming this super-useful herb will ensure that all your throat-related issues disappear overnight!


For treating respiratory issues like cough, cold, asthma, etc., simply prepare a Vacha kadha. Take a small piece of Vacha roots, 4-5 Tulsi leaves, and a pinch of black pepper powder and boil in water for some time. Consume this kadha (decoction) for lasting relief.

Stomach Worms / Gastric Issues

For treating various stomach-related issues, take 2 teaspoons each of dhania (coriander) powder and saunf (fennel) powder. Then add 2-3 gm of Vacha root pieces to it and mix this mixture in 2 kilos of water. Let it boil for some time and consume twice a day for best results. Alternatively, you can grind Vacha in pure and organic castor/coconut oil and apply on the stomach. Doing so reduces swelling of the stomach due to gas accumulation.


Everyone knows that piles can be quite painful to bear. To treat piles, take little Vacha powder and ajwain, and consume it on an empty stomach every morning.

Fever And Cold

For treating cold, prepare a paste of Vacha powder with water and apply on the top section of the nose. Plus, you can also take a few pieces of Vacha, 1-2 laung (clove), and little ginger and make a kadha out of it. Consuming this kadha (decoction) helps to treat fever and cold.


To treat epileptic episodes, take 1/2 gm Vacha Churna (powder), and consume twice a day with either milk/water.


Small children oftentimes end up getting diarrhoea. In such a case, take Vacha root and burn it till it gets reduced to a powdery ash. Take 250 mg of this ash and add 1 teaspoon of honey to it and let your child lick this mixture.

Tooth pain related to the extraction

To treat tooth-extraction related pain, take 1/2 gm Vacha powder and heat suhage ki khaal on a Tawa till it swells up. Grind the latter to a fine powder. Mix both these powders and apply on the affected area for immediate relief.

Delayed Delivery

To treat pain due to delayed delivery, you can prepare a Vacha paste and apply on the navel area. This also helps to induce labour as it promotes strong uterine contractions.
