Lemongrass: The Grass That Opens the Road
Lemongrass is a cleansing herb that clears away stagnation and opens the way to new opportunity, best known as the heart of Van Van — the signature road-opening formula of New Orleans Hoodoo tradition.
Clear the Stagnation, Open the Way: Lemongrass's Place in Cleansing
Most cleansing herbs do one thing: they remove. They cut, they drive out, they reset. Lemongrass does something more specific — it clears what is stuck and then leaves the door open, so what you actually want can walk in. That double action is the core of its magical identity, and it is what separates it from the other cleansing herbs in practice. You use lemongrass not when you simply need a space emptied, but when you need what comes next to be better than what you are clearing out.
Compare it to two of its neighbors relatives in the cleansing family. Lemon is cutting — sharp, incisive, the right tool after an argument or an illness that left residue behind. Lemon severs. Vervain is ceremonial consecration — it purifies ritual tools and altars rather than doing heavy-duty clearing. Vervain sanctifies. Lemongrass does neither of those things. It opens. It moves stagnant energy toward the exit and pulls fresh current in behind it, all in one gesture. That is a specific and genuinely useful function.
Its correspondences reflect that function directly. Cunningham places lemongrass under Mercury and air, which maps cleanly onto what it does: Mercury governs movement, communication, and the opening of paths, and air is the element of circulation and change. Wednesday, Mercury's day, is its natural timing. Its secondary category is Prosperity and Success — not because it is a money herb in the conventional sense, but because clearing a blocked road is exactly how opportunity arrives. The opening is the prosperity work. Botanically, lemongrass is Cymbopogon citratus, a true grass in the Poaceae family, related to East Indian lemongrass, citronella, and vetiver.
Van Van and the Missing Vervain
Lemongrass is the backbone of Van Van, the best-known road-opening formula in New Orleans Hoodoo — sometimes called Algiers-style Hoodoo to credit its specific regional roots. Van Van is used to clear away evil and bad conditions, open the road to new opportunities, turn bad luck good, and strengthen other charms and workings. It is one of those formulas whose name outlasted its original ingredients. The name Van Van is widely understood to be a Creole pronunciation of verveine — the French word for vervain, the European herb that lemongrass replaced in the Americas. Lemongrass was the New World substitute that arrived and stayed, its sharp citrus brightness doing in a tropical climate what vervain's astringent bite did in European soil.
There is no single correct Van Van recipe, and it would be wrong to present one as the original. The formula varies by practitioner, tradition, and supplier, and some versions include vetiver alongside lemongrass, which adds a grounding, earthy depth to the bright citrus opening. What stays consistent across versions is the intention — clear the way, open the road, flip the luck — and lemongrass, with its specific opening quality, is always at the center of that work. If you are working with Van Van, you are working with lemongrass. And if you are working with lemongrass, you are working in the direct current of that Hoodoo tradition, whether you use a commercial formula or dress your own tools.
Rooting a Stalk, and Handling the Oil
The most practical piece of information about lemongrass for a working practitioner is this: the fresh stalks sold in grocery stores and Asian markets will often root in a glass of water. Set a stalk in a couple of inches of water, keep it in a warm, bright spot, and within a week or two you will see roots forming at the base. Once those roots reach an inch or two, pot the stalk into well-draining soil, give it full sun and consistent water, and it will grow into a substantial clump. This matters because lemongrass grown at home is lemongrass you have watched and tended — it carries your attention and intention in a way a dried bag from a shelf cannot fully replicate. It wants warmth and does not survive hard frost outdoors, so in colder climates it either comes inside for winter or is grown as an annual. It grows vigorously in a large pot on a sunny balcony or patio during the warm months.
The leaf and the tea are safe in culinary use, and lemongrass tea is widely consumed without issue. The essential oil is a different matter. Its main active compound, citral, is a strong sensitizer — meaning it can cause skin reactions, particularly with repeated exposure or when used undiluted. Always dilute the oil in a carrier before applying it to a candle or to skin, and use it lightly. Concentrated lemongrass oil is harmful to cats and dogs, so it should not be diffused in a room where pets have access and should be stored well out of reach. A few drops in a floor wash or on a dressed candle poses no meaningful risk to you; a diffuser running for hours in a small room is a different matter entirely if you share your home with animals.
Three Road-Opening Workings
The Front-Step Wash
Use this when a space feels stuck — nothing moving, no opportunities arriving, a dullness that lingers after other cleansing has been done.
Brew a strong infusion of dried lemongrass by pouring boiling water over a generous handful and letting it steep until cool, then strain it into a bucket with enough additional water to work with comfortably. Begin at the back of your home — the room farthest from the front door. Wash the floors or wipe down the baseboards moving forward through the space, always working toward the front. You are sweeping stagnation toward the exit. When you reach the front door, mop over the threshold and out onto the front step, letting the wash water run off outward into the street or yard. Leave the front door open for a few minutes after. The two halves of the work are visible in the motion itself: you clear going forward, and you leave the way open behind you. Do this on a Wednesday morning for the clearest Mercury alignment, or whenever a stuck period has run long enough.
A Wednesday Candle Dressed With Lemongrass
Use this before an interview, an application, or any communication that needs to reach someone and land well.
Take a yellow or orange candle — yellow for Mercury's clarity, orange if you want the push of opportunity alongside it. Dilute a few drops of lemongrass oil in a neutral carrier and dress the candle by working the oil from the base toward the wick, drawing the intention toward you. Hold the candle for a moment before lighting it and state clearly what you need opened: the path to the role, the response to the message, the door you need someone to walk through. Light it on a Wednesday morning or during a Mercury hour for the sharpest timing. Van Van oil is traditionally used to strengthen charms and workings alongside this kind of road-opening work — if you have it, a small amount on the base of the candle or on the petition beneath it reinforces the intention. Let the candle burn as long as you can supervise it safely, then snuff it if needed and relight at the same hour the following day.
The First-Morning Cup
Use this on the first morning of something new — a job, a move, a project, a relationship — when you want the road ahead to stay open and the beginning to carry momentum.
Brew a cup of lemongrass tea from fresh or dried leaf, using water just off the boil. While it steeps, hold the cup in both hands and let your attention settle on what is beginning. Not what you are leaving — what you are entering. Drink it slowly and deliberately, treating each sip as an affirmation that the road is open and that you are moving forward through it. This is a simple working, and its simplicity is the point: the intention is clear, the herb is doing what it does, and you are marking the beginning consciously rather than letting it pass unremarked. If you want to build this into a fuller ritual with a structured ceremony around the cup, the lemongrass tea ceremony for money gives you that structure in detail.
Cleansing That Points Somewhere
Most cleansing work ends when the unwanted thing is gone. Lemongrass is the exception — its cleanse ends facing forward. The road-opening quality is not a bonus function added onto the clearing; it is the whole point. This is the herb you reach for when clearing alone is not enough, when what you need is not just an empty space but an open one. That distinction is worth sitting with, because it changes how you sequence your workings and what you reach for first.
Lemongrass belongs to the Cleansing and Purification category alongside eleven other herbs, each with its own specific angle — smoke that resets, water that washes, scent that consecrates.
