Revolutionary Natural Cold Support That Works Before Symptoms Take Hold

Stop chasing cold symptoms and start getting ahead of them naturally.

Karl’s Formula is the first dual-action ear drop designed to support your body at the very first sign of imbalance – before fatigue, head pressure, and sinus sensitivity develop into full symptoms.

Why Choose Ear Drops?

While most people overlook the ear as a therapeutic gateway, naturopathic practitioners have long recognized its unique responsiveness to gentle, natural therapies. The ear canal provides direct access for both local and systemic support.

Simple Application: 6 drops in each ear at the first hint of imbalance, up to 3 times daily.

Dual-Action Natural Formula

Gentle Oxygenation: 3% food-grade hydrogen peroxide creates an optimal environment for your body’s natural defenses while promoting clarity and cleansing.

Homeopathic Support: Three precisely selected remedies work synergistically:

  • Ferrum Phosphoricum 6C – Supports the initial phase of inflammation
  • Natrum Muriaticum 30C – Addresses dry nasal passages and sinus comfort
  • Kali Sulphuricum 30C – Supports recovery from lingering concerns

Clean Ingredients You Can Trust

No synthetic chemicals or artificial preservatives
Alcohol-free and gluten-free
Vegan-friendly formulation
Made with structured, reverse osmosis-filtered water
HPUS-compliant homeopathic remedies
Crafted in small batches with medical-grade ingredients

Perfect For:

  • Health-conscious families seeking natural alternatives
  • Frequent travelers who need reliable, non-drowsy support
  • People sensitive to conventional medications
  • Anyone wanting to act early instead of waiting until symptoms develop

Premium Packaging

Each 1-oz bottle comes in a frosted green glass dropper bottle with UV-blocking properties. Eco-conscious design meets premium functionality in a travel-ready size that fits perfectly in your medicine cabinet, purse, or carry-on.

The Karl’s Formula Difference

Proactive vs Reactive: Work with your body before symptoms take hold, not after you’re already struggling.

Gentle vs Harsh: Clean, natural ingredients that support rather than suppress your body’s wisdom.

Effective vs Drowsy: Stay clear, focused, and present while your body maintains its natural balance.

Directions for Use

Apply 6 drops in each ear at the first sign of imbalance such as fatigue, head pressure, or sinus sensitivity. May be used up to 3 times daily. For best results, use at the earliest signs rather than waiting for full symptom development.

Storage: Store in a cool, dry place away from direct sunlight. The frosted glass bottle provides natural UV protection.
