WHY NO PG?

Why a Single-Ingredient Herbal Diffuser Pen Matters

Most herbal pens on the market pack 18+ essential oils, synthetic vitamins, and artificial additives into a single device. At 5:1 Formulas, we simplify the process to honor age-old herbalism with modern diffusion technology.

  • One Herb Per Formula

    No blends. No guesswork. We believe it's unsafe to blend 18+ essential oils and vitamins into one diffuser.

  • No Fillers or Additives

    No artificial flavors, no unnecessary ingredients. One Powdered Herb + Organic Vegetable Glycerin.

  • Lab Tested

    Every formula is tested for quality and consistency.

  • Clean, Transparent Composition

    Know exactly what you’re using — nothing hidden.

TRANSPARENCY & ANSWERS

Herbal Diffuser Pen FAQs Single-Herb Formulas & Ingredients

 Everything you need to know about our lab-tested, nicotine-free herbal diffusers, single-ingredient botanical formulas, and how 5:1 compares to traditional herbal vape pens.
A herbal diffuser pen is a personal, handheld botanical device designed to deliver a clean, aromatic plant experience. Unlike conventional diffusers that mix 18 or more essential oils, synthetic vitamins, and artificial flavorings into one blend, every 5:1 herbal diffuser features just one single powdered herb suspended in organic vegetable glycerin, giving you a pure, transparent botanical profile with nothing hidden.

While many shoppers search for an herbal vape, herbal vape pen, or herbal vape no nicotine when looking for a plant-based alternative, 5:1 Formulas is strictly a botanical herbal diffuser, not a tobacco or nicotine product. Our herbal pens contain zero nicotine, zero tobacco, zero THC, zero CBD, and zero propylene glycol (PG), and they are designed to promote general wellness rather than simulate smoking.
Next, add document buttons to display your lab results and certificates
Every 5:1 herbal diffuser pen is made with only two ingredients: One 100% pure, single-origin powdered herb (such as Chamomile Flower, Mullein Leaf, Yerba Maté Leaf, or Lavender Flower). Organic vegetable glycerin.
Next, add document buttons to display your lab results and certificates
Propylene glycol (PG) is a synthetic carrier liquid commonly used in standard vape products that can feel harsh on the throat. Similarly, inhaling concentrated essential oil blends, especially formulas combining a dozen or more oils, adds unnecessary complexity and potential irritation. By pairing a single powdered herb with organic vegetable glycerin, our herbal diffusers deliver a smoother, cleaner, and more predictable botanical experience.
Next, add document buttons to display your lab results and certificates
Yes. Every batch of 5:1 Formulas is independently third-party lab tested for heavy metals, pesticides, residual solvents, and microbiological contaminants. You can view our Certificates of Analysis (COAs) directly on our website under Transparency / View Lab Results to verify the purity of your exact formula before you use it.
