Smokable Herbs You Can Vape: 15 Herbs With Starting Temperatures

Most herbs you can smoke, including mullein, damiana, chamomile, lavender, peppermint, lemon balm, garden sage and hops, also work in a dry herb vaporizer, where you taste them instead of burning them. Storz & Bickel's own manuals list settings from 130°C (266°F) for eucalyptus and lavender up to 190°C (374°F) for chamomile, sage and thyme. For herbs no maker lists, start at 160°C (320°F), step up 10 degrees at a time, and stop by 200°C (392°F).

Herb vaping temperatures get repeated all over the web and are almost never sourced. The figures that hold up trace back to two vaporizer makers, Storz & Bickel and Arizer, so those are what we use, checked against the boiling points of each herb's main aroma compounds on PubChem. We haven't run these herbs through our own devices for this guide; it's built from manufacturer documentation and published chemistry, and every number is a starting point. It covers flavor and safety, not effects, and none of it is medical advice.

15 Smokable Herbs and Where to Start Them

"Start at" is the lowest figure a maker publishes for that herb. Where no maker lists it, we use 160°C (320°F), the top of Arizer's range for its aromatic botanicals. Storz & Bickel's figures come from the plant table in the current Volcano Hybrid manual, which the Mighty+ and Crafty+ manuals repeat; Arizer's come from its botanicals chart.

On a Volcano Classic, Storz & Bickel's manual maps its figures to the dial: 1 for eucalyptus and lavender, 2 for lemon balm, 3 for hops, and 6 for chamomile, sage and thyme. Our guide to using a Volcano vaporizer covers the rest of the machine.

Why the Maker Settings Sit Below the Boiling Points

Next to the chemistry, the makers' numbers look low. Here are the main aroma compounds behind these herbs, with atmospheric boiling points from PubChem:

That isn't a contradiction. Aroma compounds evaporate well below their boiling points, the way a puddle dries without boiling, which is also why THC leaves flower below its own boiling point; our terpene boiling points chart covers the physics. The low settings catch the lightest aromatics first, and the heavier compounds explain why peppermint and thyme keep their character as you step up.

They also explain why there's nothing to chase at the top. Several of these compounds boil above 230°C (446°F), the point where cannabis combusted in the Cal NORML and MAPS bench test, and Storz & Bickel's manuals call a higher temperature a last resort because the plant material starts to taste burnt. No maker lists any of these herbs above 190°C, which is why we stop at 200°C.

Two of the compounds, linalool and myrcene, are major cannabis terpenes too, which is part of why lavender and hops sit so comfortably next to flower. Our vaporization temperature calculator shows where they come in alongside the cannabinoids.

How to Vape Herbs Without Toasting Them

The routine is the same as for flower, which our guide to using a dry herb vaporizer walks through. What changes is the temperature, and the device has to be able to go that low.

The Venty, Mighty+ and Volcano Hybrid start at 40°C, the Arizer Solo 3 at 50°C and the XMAX V3 Pro at 100°C, so they cover the whole table; the Tinymight 2 starts at 140°C, close enough. The PAX 3 and PAX Plus start at 182°C (360°F), above most of it. A DynaVap clicks around 240°C, too hot for anything here. Convection suits leaves and petals because hot air passes through them instead of the oven wall scorching whatever touches it; convection vs conduction explains the difference, and the best convection vaporizers list is a good start, as long as you check each device's lowest setting.

1. Grind fine. Storz & Bickel's manuals say the finer the plant is ground, the more aroma it releases. Dried leaf and petals are bulky, so a full chamber weighs less than flower.
2. Pack evenly and lightly. Light leaf can shift in a convection device, so fill to the top and level it without cramming.
3. Start at the table's figure. Take a slow draw, then step up 10°C every few draws as the flavor fades.
4. Stop by 200°C (392°F). If it tastes burnt before that, drop back and pack fresh next time.
5. Clean after strong herbs. Mint, eucalyptus and lavender can linger in the vapor path, so brush and swab afterward, following how to clean a dry herb vaporizer.

Tip: Keep one or two dosing capsules just for herbs. The herb never touches the chamber, so your next bowl of flower doesn't taste of peppermint.

Why Vape Herbs Instead of Smoking Them

Burning a plant makes smoke whatever the plant is. When the Federal Trade Commission went after herbal cigarette marketers in 2000, the disclosure it required on herbal cigarette packs was blunt: "Herbal cigarettes are dangerous to your health. They produce tar and carbon monoxide."

A vaporizer heats below combustion, so you inhale the evaporated aroma instead of burning leaf. The research comparing vapor with smoke is on cannabis, though, not chamomile or mullein, so we won't claim a health benefit for any of these herbs. What you can count on is flavor: at 130 to 190°C you taste the lavender, not burning paper and leaf. Our guide from smoke to vapor covers the switch in general.

"Mullein Vape" Pens Are a Different Product

Search "mullein vape" and many of the results are liquid pens, sometimes sold as herbal diffusers: typically a cartridge of glycerin or propylene glycol with plant extracts, essential oils or flavorings, heated on a coil. They're closer to a nicotine-free e-cigarette than to a dry herb vaporizer, and nothing in this guide applies to them. If the product has a tank, a cartridge or a liquid ingredient list, it isn't dried mullein leaf.

Safety: Allergies, Pregnancy and Where to Buy

• Allergies. Chamomile and mugwort belong to the daisy family alongside ragweed. NCCIH notes that people allergic to ragweed, chrysanthemums, marigolds or daisies are more likely to react to chamomile, and mugwort pollen is itself a major allergen. Storz & Bickel's Volcano manuals warn that some plants cause allergic reactions and say to stop using any that do.
• Pregnancy, breastfeeding and medication. NCCIH says passionflower should not be used during pregnancy and that sage may be unsafe then because of its thujone. The European Medicines Agency's mullein monograph doesn't recommend it in pregnancy either, and it covers the flower as a tea, not anything inhaled. Our advice: skip herbal inhalation while pregnant or breastfeeding, and ask a pharmacist first if you take prescription medication.
• Buy food-grade dried herb. Storz & Bickel's manuals ask for plant material tested for authenticity, purity and pathogens to European Pharmacopoeia standards. A tea or herb supplier selling organic or food-grade leaf is the practical version. Arizer, for one, sells chamomile, lavender, peppermint, eucalyptus and rose petals for vaporizers at $4.24 for 12 grams or $7.22 for 24 grams as of October 2026.
• Don't forage, and skip florist flowers. Wild plants are easy to misidentify, and roadside or ornamental plants can carry pesticides you don't want to heat and inhale.
• No essential oils. Oils are far more concentrated than the dried plant, they gum up screens, and the makers' temperature tables are for dried plant material.

Warning: Keep eucalyptus to the dried leaf. Eucalyptus oil is a known poisoning risk if swallowed, so keep any bottle well away from children.

What We Left Out, and the Legal Fine Print

Salvia divinorum, kratom, blue lotus and other herbs sold for a psychoactive effect aren't on this list: several are restricted by state law, and the FDA warns consumers not to use kratom at all.

Two herbs that are on the list carry a legal catch. Louisiana's prohibited plant law names mugwort and damiana, alongside Salvia divinorum, kratom and blue lotus, and bans possessing them prepared for smoking or for burning and inhaling, as well as selling them for use in a pipe, cigarette or other device. If you're in Louisiana, leave both out. Everything else here is sold as ordinary tea or kitchen herbs, but laws vary, so check yours. This isn't legal advice.

Blending Herbs With Cannabis or CBD Flower

Plenty of people use these herbs in a blend with flower. A typical herbal smoking blend pairs a mild base like mullein or raspberry leaf, which stretches the flower and lowers the strength of each bowl, with a flavor herb like spearmint or lavender. The math is simple dilution: a 20 percent THC flower mixed half and half by weight with mullein works out to about 10 percent. Our flower blending calculator does it for any ratio if you enter the herb as the second flower with zero THC and zero CBD.

Temperature is the compromise. Set for the cannabis, but open at the low end of its range, around 170 to 180°C (338 to 356°F), so you taste the herb before it toasts, then step into your usual range; what temperature to vape flower covers that side. CBD flower wants 200 to 220°C for fuller extraction, above any maker's figure for these herbs, so treat the herb as the opening flavor. Every pick on our list of the best vaporizers for CBD flower reaches 220°C.

Frequently Asked Questions

What herbs can you smoke or vape?

Mullein, damiana, chamomile, lavender, peppermint, spearmint, lemon balm, garden sage, thyme, mugwort, passionflower, raspberry leaf, rose petals, hops and eucalyptus are the common ones, and all of them work in a dry herb vaporizer that goes low enough. Start between 130 and 190°C (266 to 374°F) depending on the herb and stop by 200°C (392°F).

What is the best smokable herb to start with?

Mullein or raspberry leaf, because they're mild and close to neutral, which is why they're the usual base for blends. Add a pinch of a flavor herb like spearmint or lavender once you know what the base tastes like on its own.

Can you vape mullein?

Yes. Dried mullein leaf works in any dry herb vaporizer. No maker publishes a figure for it, so start at 160°C (320°F) and stop by 200°C, with the screen in. Liquid "mullein vape" pens are a different product.

Can you vape lavender and chamomile?

Both appear in manufacturer charts. Storz & Bickel lists lavender at 130°C (266°F) and chamomile at 190°C (374°F), while Arizer puts both at 130 to 160°C. Start low and step up, and skip chamomile if you're allergic to ragweed.

Is vaping herbs safer than smoking them?

Vaping avoids combustion, and smoke from any burning plant contains tar and carbon monoxide. But the studies comparing vapor with smoke were done on cannabis, not on these herbs, so there's no evidence-based safety claim to make for them. Nothing here is medical advice.
