Let’s just get this out of the way: most sinus sprays are garbage. Either they’re glorified saline, packed with chemicals you can’t pronounce, or they give you a 15-minute window of relief before you’re back to mouth-breathing like a caveman.
So when my uncle—a chiropractor with decades in the trenches of natural healing and traditional Chinese medicine—handed me a little bottle of Lassen’s Sinus Blaster Spray and said, “This stuff actually works,” I paid attention. The man’s seen more immune systems than I’ve seen Netflix suggestions, and he doesn’t waste time with hype.
I tried it. It tasted like a disgusting mix of onions, garlic and ethereal oils. And then my sinuses opened up like floodgates.
Now, every time I feel something creeping in—scratchy throat, pressure behind the eyes, that weird flu-y fog—I reach for the Sinus Blaster. A couple sprays in the mouth, spaced throughout the day, and nine times out of ten, I don’t get sick. It’s not subtle. It’s not sweet. But it is shockingly effective.
Let’s break down what makes this tiny herbal nuke so powerful—and why it might earn a permanent spot in your cold-season toolkit.
What the Hell Is Lassen’s Sinus Blaster?
Lassen’s Sinus Blaster Spray is what happens when you take herbal medicine seriously—and give it a slight attitude problem.
It’s a professional-strength herbal supplement, made by Lassen’s Natural Foods & Vitamins in Ventura, California. If you’ve never been to Lassen’s, picture an old-school health food store run by people who actually walk the walk: organic, locally sourced, zero corporate fluff. The Sinus Blaster is one of their in-house formulas, and it’s not here to coddle your symptoms—it’s here to light them up.
Unlike most sinus sprays that go up your nose, this one goes in your mouth. That might sound weird, but there’s a reason for it (which we’ll get into later). You spray it directly under your tongue or toward the back of your throat, let it sit, and wait for the herbal hammer to drop.
The formula is all plant-based, no synthetic junk, and designed to hit the core problems: inflammation, microbial buildup, and that slow, foggy immune response that lets a little sniffle turn into a full-blown flu.
In short: it’s not playing around. And that’s exactly why it works.
The Core Blend (aka the Herbal Hit Squad)
Fresh Horseradish Root
Instant sinus detonation. Horseradish is like a natural decongestant with a vengeance. It stimulates mucus flow, clears up nasal passages, and leaves your head feeling like it got pressure-washed.
Echinacea Angustifolia Root
Your immune system’s hype man. Echinacea doesn’t cure anything, but it does rev up your white blood cell response—especially helpful when you’re on the verge of getting sick.
Fresh Spilanthes Herb
Also known as the “toothache plant,” this one creates a tingly, numbing sensation that stimulates salivation and mucosal circulation. It feels intense—and that’s part of the magic.
Elderberry Fruit
Antioxidant-rich and antiviral, elderberry is a winter wellness staple for a reason. It helps your body recognize and respond to viral threats faster.
Garlic Bulb
Nature’s antibiotic. Antiviral, antibacterial, antifungal—and in this case, anti-flu. Garlic’s sulfur compounds like allicin make it a frontline defense tool.
Cayenne Fruit
Capsaicin thins mucus, reduces inflammation, and wakes up your system like a fire alarm. If this spray burns a little, you can thank cayenne.
Peppermint Oil
Menthol opens airways and provides that icy-cool contrast to the horseradish heat. It’s also antimicrobial and a digestive aid bonus.
Olive Leaf
Known for its antiviral and antimicrobial effects. This is the quiet immune modulator in the background, doing work.
Horehound Herb
Old-school cough remedy. Helps loosen mucus and soothe the respiratory tract.
Licorice Root
Anti-inflammatory, slightly sweet, and soothing to mucous membranes. Also balances out the burn.
Goldenseal Root
A powerful antimicrobial often used alongside echinacea. Helps your system respond fast to bacterial invaders.
Wild Cherry Bark
Soothes the throat, calms coughing, and supports respiratory health. Think of it as the cooldown lap after cayenne.
Fresh Osha Root
Used for centuries in Native and Western herbalism to support deep lung function. Earthy, strong, and effective.
Andrographis Herb
One of the heaviest hitters in herbal immune support. Often used in Ayurvedic and Chinese medicine for viral infections and upper respiratory issues.
Onion Bulb
Yeah, the kitchen staple. It’s anti-inflammatory, anti-everything, and surprisingly effective when concentrated.
Yarrow Herb
An unsung hero for immune support and inflammation modulation. Often overlooked, but solid.
Other Ingredients
- Grain Alcohol (37–47%) – Acts as a solvent to extract and preserve the herbs—and yeah, it also gives the spray some kick.
- Deionized Water – Clean and pure, used to dilute the formula.
- Vegetable Glycerin – Adds a little smoothness and helps coat the mouth/throat.
- Organic Honey – Slightly sweetens the burn, and adds natural antimicrobial support.
Herb Strength Ratio: 1:2.9 — That’s strong. This isn’t a “just vibes” tincture. It’s concentrated, potent, and made to actually do something.
The Experience: What It Feels Like to Use It
Using Lassen’s Sinus Blaster for the first time is a little like jumping into an ice bath—you don’t do it for comfort, you do it for results.
Here’s what to expect:
Step One: The Spray
You aim it at the back of your mouth or under your tongue, squeeze the pump, and—boom—it hits. The taste? Sharp onion-ish, spicy, herbal, with a heavy hint of garlic and peppermint. You’re not mistaking this for bubblegum-flavored anything. This stuff tastes like it was brewed in the forest by a slightly unhinged herbalist—and that’s a compliment.
Step Two: The Burn
Give it a few seconds. The horseradish and cayenne start to kick in. Your eyes might water. Your sinuses will tingle. You’ll probably question your life choices.
But then… the clearing starts.
You’ll feel pressure behind your eyes release. Nasal passages open up. That foggy, congested feeling starts to lift. It doesn’t just treat the symptom—it feels like it’s going to war with whatever’s creeping up your nose and throat.
Step Three: The Aftermath
About 10–15 minutes later, you realize you can breathe more clearly. If you caught something early—maybe that tickle in your throat or that drained, pre-flu fatigue—it often stops it in its tracks. For real.
Used two or three times throughout the day at the first sign of a bug, this spray has saved me from full-blown colds more times than I can count. It’s not a magic wand, but it’s damn close when used right.
TL;DR: What It’s Like
- Taste: Spicy, earthy, intense, and oddly disgusting
- Sensation: Hot, clearing, wake-the-hell-up type of feeling
- Speed: Works within minutes for congestion relief
- Best used: At the very first sign of a cold or sinus pressure
The Science: Why It Might Actually Work
Let’s be real—just because something feels intense doesn’t mean it works. But in the case of Lassen’s Sinus Blaster, there’s legit science behind why it does more than just slap your senses awake.
It Hits Inflammation Head-On
Sinus congestion isn’t just about mucus—it’s about inflammation. When your sinuses swell up (usually thanks to an immune response), everything gets blocked, pressure builds, and you feel like your skull’s being squeezed from the inside.
Ingredients like goldenseal, licorice root, and yarrow are loaded with bioactive compounds that modulate inflammation. Translation? They help turn the dial down on your body’s overreaction before things spiral into a full-blown sinus infection.
It Supports the Immune System—Fast
Herbs like echinacea, andrographis, and elderberry are known immune stimulants. They basically tell your body, “Hey, something’s coming—get your immune army moving.”
These herbs don’t wait around for things to get worse. They prime your immune response early, which is exactly when you want to intervene—during that first tickle, that first wave of fatigue, the first hint that something’s off.
It Clears Mucus and Opens Airways
This part is simple cause and effect. Horseradish, cayenne, and peppermint oil trigger a physiological reaction—think mucus thinning, vasodilation (widening of blood vessels), and increased circulation.
What does that feel like? Relief. Less pressure. Less fog. Easier breathing.
Sublingual Delivery = Fast Absorption
Here’s where the spray format actually matters. By spraying into your mouth—especially under the tongue—you bypass a lot of the slow, inefficient digestive process. The mucous membranes in your mouth are super porous, which allows active compounds to enter the bloodstream faster.
This is the same reason why things like CBD oil and nitroglycerin are taken sublingually. It’s not a gimmick—it’s a legit fast-track.
It Combines Synergistic Herbs
This isn’t one ingredient doing all the work—it’s a strategic combo. Some herbs fight bacteria. Others reduce inflammation. Some open airways, others activate immune cells. That “stacked” effect is what gives it the power to actually change your trajectory when you’re starting to get sick.
Who This Is (and Isn’t) For
Let’s be honest: Lassen’s Sinus Blaster Spray isn’t for everyone. This is not some gentle, lavender-scented “wellness” product you find in a gift basket. It’s strong. It’s spicy. It’s herbal warfare.
If that sounds like your vibe, read on.
This is for you if:
- You’re the kind of person who takes action the second something feels off—scratchy throat, sinus pressure, mental fog.
- You’ve tried every over-the-counter sinus spray and came away disappointed, still congested, and $14 poorer.
- You value natural, plant-based solutions but still want something that actually does something.
- You’re into biohacking, functional medicine, or just want to keep your immune system sharp without nuking your gut with antibiotics.
- You travel a lot, are exposed to sick people often, or have kids (aka walking germ factories).
- You don’t mind a product that punches a little on the way in, as long as it works.
This might not be for you if:
- You’re sensitive to spice, heat, or intense herbal flavors. This stuff hits hard.
- You think “natural” means mild, sweet, and soothing. That’s not this.
- You want a long-term daily supplement. This is more of a tactical strike—not a multivitamin.
- You have major allergies to any of the listed herbs (always read the label, obviously).
The bottom line
If you’re okay with a product that’s not here to coddle you, and you’re looking for something that actually works when your sinuses go to war, this stuff is worth keeping in your wellness arsenal.
Final Verdict
Lassen’s Sinus Blaster Spray isn’t subtle. It doesn’t whisper sweet nothings to your immune system. It shows up with a blowtorch, kicks your sinus congestion in the teeth, and leaves your head feeling like someone cracked open a window in your skull.
And I mean that in the best way possible.
It’s one of those rare natural remedies that doesn’t just rely on placebo and branding. The ingredients are strong. The delivery method is smart. The effect is real. And for me—introduced by a trusted uncle who’s spent decades in natural medicine—it’s become one of those don’t-leave-home-without-it tools.
Is it intense? Yeah. But so is getting sick.
If you’re someone who wants to stay ahead of colds, crush sinus pressure fast, or have something in your kit that actually does something when you’re starting to feel off, this stuff earns its spot.
Where to get it
You can find it at Lassen’s Natural Foods (if you’re in California), or online through a few herbal retailers. It’s not mass-market, and that’s part of the charm.
Pro tips for first-time users
- Start with 1 spray, not 2. Trust me.
- Don’t chase it with water—let it sit under your tongue or in your mouth for 20–30 seconds.
- If you’re using it preventively, 2–3 times per day is plenty.
- Keep it in your bag during travel or cold season.
