The Five Botanicals in BreathiZen: A Plain-English Profile

Updated October 2026

A quick map of the formula

BreathiZen is a stimulant-free botanical formula, delivered as a sublingual spray in a 2 oz / 60 ml amber bottle. The brand names five ingredients and publishes no amounts, so we describe each one in general terms and leave the specifics to the Supplement Facts panel on the bottle, which shows the full details.

We describe what each ingredient is and where it comes from, nothing more. For the brand's own overview, see the ingredients guide, and for the bigger picture visit BreathiZen explained.

Mullein Leaf Extract (10:1)

Mullein is a tall, hardy plant with soft, velvety, gray-green leaves and a spike of small yellow flowers. It grows across parts of Europe and Asia and has spread widely, often seen along roadsides and in open fields. The label lists an extract made from the leaf.

In traditional herbal literature, mullein appears under many folk names, and its tall stalks make it easy to spot in a summer meadow. For our purposes, the key facts are simple: it is a plant, it has soft leaves, and the ingredient comes from the leaf.

The "10:1" tells you about preparation. In general, an extract ratio like this describes how much raw plant material was used to make the extract. It is a description of the extract, not an amount per spray.

Ginger Root Extract

Ginger is a flowering plant whose underground stem, called a rhizome, is the knobby "root" sold in grocery stores. It is native to Asia and is a staple in kitchens around the world, appearing in stir-fries, teas, baked goods and pickles. You can find a plain overview on the NCCIH ginger overview.

BreathiZen lists Ginger Root Extract, meaning an extract prepared from that familiar root. For kitchen ideas, see our post on citrus and ginger kitchen ideas.

Bromelain (2400 GDU/g, from pineapple stem)

Bromelain is a group of enzymes found in the pineapple plant. The ingredient on the BreathiZen label comes from the stem rather than the sweet fruit we eat, which is a common source for this kind of ingredient.

The figure "2400 GDU/g" is a measure of enzyme activity. GDU stands for gelatin digesting units, a standard laboratory way of describing how active a bromelain ingredient is per gram. Like the 10:1 on mullein, it describes the ingredient itself, not the amount in each spray.

Organic Lemon Extract

Lemon is a citrus fruit that grows on small evergreen trees in warm regions. Its bright, tart juice and fragrant peel are everyday kitchen staples, used in dressings, drinks, desserts and marinades. The label lists Organic Lemon Extract, and "organic" refers to how the lemons were sourced.

Citrus fruit is one of the most widely grown fruit crops in the world, and lemon in particular has been a pantry favorite for generations. Even a single lemon can flavor a week of meals.

Lemon is also the easiest ingredient on the list to bring into your own kitchen: a wedge in a glass of water, zest over roasted vegetables or juice in a salad dressing.

Organic Cordyceps militaris

Cordyceps is a genus of fungi, and Cordyceps militaris is one well-known species, recognizable by its small, orange, club-shaped fruiting bodies. Today it is commonly grown under controlled conditions. The label lists it as organic, which describes the sourcing.

In the wild, species of this genus grow in forests, while commercial supplies usually come from cultivation, which allows a consistent, controlled product from batch to batch.

Of the five names, this one is probably the least familiar. That makes it a good example of why a plain-language profile is useful: the name sounds exotic, but the description is simple. It is a fungus, grown and used as an ingredient.

What to do with this information

Now that the five names are familiar, the Supplement Facts panel will be easier to read. Our guide to reading the Supplement Facts panel walks through it step by step. For general background on supplement ingredients, the NIH Office of Dietary Supplements is a trusted starting point, and NCCIH: using dietary supplements wisely is a good read for new shoppers.

The brand directs 4 sprays daily at about the same time each day, preferably under the tongue, and the product is designed to support daily lung wellness. If you are ready to try it, see the BreathiZen packages. Every package is a one-time purchase with a 60-day money-back guarantee.
