Rosha Grass for Gas and Flatulence: Does It Work?
Does Rosha Grass (Rohisha) help with gas and flatulence? It is a sensible supporting herb for one pattern: heavy, slow digestion with gas. Classical sources describe this lemon-scented grass as a stimulant, a carminative (something that relieves gas) and a digestive.
The Bhavaprakash Nighantu lists it as an appetizer that kindles the digestive fire (Deepana) and as reducing Kapha (Kaphashamaka). Its bitter and pungent taste, light and sharp qualities and hot potency (Ushna Virya) are the classical answer to a sluggish gut. Classical sources also list it for Vata disorders, and Ayurveda sees gas as Vata trapped in the colon.
Our sources give no classical verse naming Rosha Grass for gas specifically; the link comes from its carminative and digestive actions. Think of it as a gentle aromatic for cold, heavy digestion, not a first-line remedy.
How Rosha Grass Helps with Gas and Flatulence
Ayurveda places the root of most gas in weak digestive fire (Agni). Partly digested food ferments, and the wind it produces blocks Apana Vayu, the downward-moving wind of the lower abdomen.
Kindling a slow fire
Rosha Grass is hot in potency, sharp and light, with a pungent post-digestive effect (Katu Vipaka). Warm, light and sharp herbs are the classical tool for sluggish digestion, which is why the Bhavaprakash Nighantu calls it Deepana, a fire-kindler.
Clearing heaviness
As a Kapha-reducing herb, it suits the Kapha pattern of gas: bloating that appears hours after a heavy, dairy-rich meal, often with a sense of heaviness. Its carminative action helps move the trapped wind itself.
The same heat sets the limit. In Ayurvedic reasoning, herbs with this profile reduce Kapha but can aggravate Pitta. Our sources hold no modern research on Rosha Grass for gas.
How to Use Rosha Grass for Gas and Flatulence
For gas, the decoction (kashaya) of the root and leaves is the one internal form our sources describe. It is a tea made by simmering the herb in water until it reduces, then straining.
| Form | Dose | Best for |
|---|---|---|
| Decoction of root and leaves | 2 to 4 masha (classical unit of weight) | Indigestion, gas, Kapha and Vata complaints |
| Essential oil | No internal dose in our sources; do not swallow | Perfumery and external use only |
A masha is a classical Ayurvedic unit of weight. Our sources do not give a modern conversion, so ask a qualified practitioner to translate it into a measured amount.
Timing and vehicle
Our sources do not specify timing, an anupana (the vehicle a herb is taken with) or a course length for Rosha Grass. Taken warm, as a decoction naturally is, it fits the general Ayurvedic advice to keep drinks warm around meals when gas is a problem.
If you want a better documented anti-gas spice, Ajwain and Hing have clear doses and timings.
Frequently Asked Questions
Is Rosha Grass the same as lemongrass?
They are close relatives. Rosha Grass is Cymbopogon schoenanthus; the Sahasra Yoga drug index lists Rohisha under Cymbopogon martini, the source of palmarosa oil. Check the botanical name on anything you buy. See also Lemongrass for gas.
What kind of gas does it suit?
Heavy, slow, Kapha-type digestion. If your gas comes with acid reflux, burning or loose stools, this hot herb may aggravate Pitta.
Can I drink the essential oil for gas?
No. Our sources give no internal dose for the oil, which is a concentrated perfumery product. The only internal form described is the decoction of the grass.
Rosha Grass vs Ajwain for gas?
Ajwain for gas is faster and far better documented, chewed after meals. Rosha Grass is a gentler aromatic support for sluggish digestion.
Recommended: Start Rosha Grass for Gas and Flatulence

Safety & Precautions
Our sources do not list specific contraindications, drug interactions or overdose signs for Rosha Grass. That absence is not proof of safety; it means the classical texts we draw on are silent.
What its properties suggest
Rosha Grass is hot in potency (Ushna Virya), sharp (Tikshna) and pungent in its post-digestive effect (Katu Vipaka), which describes how a herb acts after digestion. In Ayurvedic reasoning, herbs with this profile reduce Kapha but can aggravate Pitta, the hot dosha. If you run hot, have acid reflux or tend toward inflammation, use it cautiously.
Essential oil
The distilled oil is a concentrated product used in perfumery. Our sources give no internal dose for the oil, so do not swallow it. The only internal dose in our sources is for the decoction of the grass.
Pregnancy, nursing and medications
Our sources do not cover use in pregnancy or while nursing, or interactions with medicines. Speak to a qualified practitioner or your doctor before using it in those situations, and do not use it in place of medical care for heart disease or fever.
