All About Herbal Bitters
You may be most familiar with using bitters in crafting cocktails, but did you know you can use them on a daily basis to ground yourself, aid digestion and have a sweet little moment of Earth connection before meals? These potent plant extracts, traditionally taken before meals - though you can take them after as well - have been used for centuries to stimulate digestion and awaken the “digestive fire” that sits at the heart of good health. In this post, we'll dive into the lore and science of bitters, their effects on both the digestive system and the vagus nerve, and even share a recipe for crafting your own bitters using plants native to the Pacific Northwest or a Simple Spiced Bitters. Grab something to drink and settle in, this is a long post with lots of delicious information!
The Power of Bitter
The bitter taste has a fascinating and complex role in our sensory and digestive systems. We believe it evolved as a natural defense mechanism, meaning that bitterness helps protect us from harmful substances since many toxins are naturally bitter. This would explain why humans are equipped with over 25 different bitter taste receptors, or TAS2Rs, distributed across the tongue, making bitterness one of the most widely detectable tastes (we only have a few for sweet, as a comparison). Interestingly, these receptors aren’t limited to the mouth; they’re also found in the stomach, intestines, lungs, and even the brain, where they contribute to various functions, including digestion and immune responses. When we taste bitterness, the body responds by releasing digestive enzymes and gastric acid, priming our system to break down and absorb nutrients. In this way, incorporating bitter flavors, like herbal digestive aids, before meals can support digestive health.

Bitterness perception varies widely from person to person, largely due to genetics. Some people, known as "super-tasters," are highly sensitive to bitter flavors, which can make foods like kale and coffee taste extra intense or even completely off putting. Thankfully I am not one of these folks and I can enjoy a good cup of joe!
Hormonal fluctuations can also impact bitterness perception, as seen during pregnancy when sensitivity to bitter flavors increases - potentially as an extra protective measure against toxins. Historically, bitterness was a regular part of our diet because early humans consumed a wider variety of wild plants, many of which were bitter or were totally new to the humans consuming them. Today, however, the modern diet is incredibly low in naturally bitter foods.
Bitter foods, beyond their distinctive taste, offer numerous health benefits. Leafy greens, cacao, and cruciferous vegetables are high in antioxidants, vitamins, and minerals, which support functions from liver health to reduced inflammation.
Actions on the Digestive System
When we taste something bitter, our brain sends messages to various digestive organs, triggering a cascade of reactions:
Saliva production increases, beginning the breakdown of starches.
Stomach acid and bile production ramps up, aiding the digestion of fats and proteins.
Peristalsis, the movement of muscles in the digestive tract, is stimulated, helping food move efficiently through the stomach and intestines.
These combined actions improve nutrient absorption, prevent bloating, and can even relieve occasional constipation. Regular use of digestive bitters supports a robust and efficient digestive system, helping you feel lighter and more energized after meals.
Digestive Fire and the Role of Bitters in Health
In many traditions, digestive health is central to overall well-being, often symbolized as a “digestive fire.” This concept comes from Ayurveda and traditional Chinese medicine, where balanced digestive fire (or “Agni” in Ayurveda) signifies the body’s ability to properly digest food and absorb nutrients. When this fire is “weak,” we’re more prone to digestive discomfort, sluggishness, and even mental fog. Digestive bitters serve as fuel for this fire, keeping it vibrant and balanced.
Bitters and the Vagus Nerve
The vagus nerve, often called the “wandering nerve,” travels from the brain to various organs, including the heart, lungs, and digestive tract. This nerve plays a huge role in the “rest and digest” state, activating many of the body’s involuntary functions that support digestion, detoxification, and relaxation.
Bitters play an interesting role here by stimulating the vagus nerve’s digestive functions. When the taste receptors on your tongue detect bitterness, it sends a direct signal to the brain, which then activates the vagus nerve to encourage digestive processes. This link between the bitter taste and vagal stimulation can promote improved digestion and may also help with managing stress.
Simple Spice Digestive Bitters Recipe
Ingredients
1 part dried dandelion root – Adds a bitter note to stimulate bile production and aid digestion. You can find this at health food stores or online.
1 part dried orange peel – Adds a pleasant citrus flavor and contains compounds that support digestive health.
1 part fennel seed – Aids in reducing bloating, gas, and soothing the stomach. Fennel has a mild sweetness that balances bitterness.
1 part ginger root (dried or fresh) – Warming and spicy, ginger is great for stimulating digestion and reducing nausea.
1 part cinnamon stick – Adds a pleasant, warming flavor that helps regulate blood sugar and has anti-inflammatory properties.
1/2 part clove – Strong and aromatic, cloves have digestive-boosting and anti-inflammatory effects.
Vodka or brandy – Enough to cover the herbs. Vodka provides a neutral taste (I like Icelandic Brand or the Kirkland French vodka), while brandy offers a hint of warmth and sweetness.
Instructions
Prepare the herbs and spices by lightly crushing them with a mortar and pestle or the back of a spoon to release their aromatic oils.
Combine all the ingredients in a clean glass jar, filling the jar halfway with your herbal mix.
Cover the herbs with alcohol (vodka or brandy) until they are completely submerged. The alcohol will act as a preservative and extract the beneficial compounds from the herbs and spices.
Seal the jar and store it in a cool, dark place for 6-8 weeks, shaking it gently every few days.
Strain the mixture through a fine mesh strainer or cheesecloth, pouring the bitters into a dark glass bottle with a dropper.
How to Use
Take 1-2 droppers (about 1/4 teaspoon) directly on your tongue about 10-15 minutes before a meal. This preps your digestive system for food, helping stimulate saliva and bile production.
PNW-Inspired Digestive Bitters Recipe
Note: you may not be able to gather all of these pieces at one single moment, so it’s okay to use some dried, or to add more plants as you’re able to harvest them freshly. In my opinion, having the Oregon grape root and the dandelion root be fresh are absolutely the most important part to preserve all that bitter goodness.
Hold the sacred when you’re harvesting anything - but especially roots.
Ingredients:
1 part Oregon grape root – An earthy, bitter root that stimulates bile flow and helps with fat digestion.
1 part dandelion root – This common, resilient root aids liver health and supports bile production, promoting smoother digestion.
1 part yarrow – A plant with mild bitter properties that also supports circulation, digestive health, and has a history in folk healing for soothing the stomach.
1 part Douglas fir tips – Young fir tips add a gentle, resinous flavor that brightens the bitter taste and provides vitamin C.
1 part ginger (optional) – This warming herb can help settle the stomach and balance the bitterness with a hint of spice.
Vodka or brandy (enough to cover the herbs) – This serves as the base for extraction, with vodka as a neutral option and brandy for a slightly richer flavor.
A glass jar with a tight-fitting lid
Instructions:
Prepare the herbs by chopping them finely, making sure they’re clean and dry.
Combine the herbs in your glass jar, filling it halfway.
Cover the herbs with vodka or brandy, ensuring all plant matter is submerged.
Seal the jar tightly and place it in a cool, dark place. Shake the jar gently every few days.
After 6-8 weeks, strain the herbs from the liquid using a cheesecloth or fine mesh strainer, and pour your bitters into a dark glass bottle with a dropper.
To Use:
Take 1-2 droppers of your bitters tincture about 10-15 minutes before meals. Place a few drops directly on your tongue to allow the bitterness to engage your taste buds fully, then swallow.
The Magic of Bitters: Beyond Digestion
Bitters are more than just a digestive aid; they are a doorway into the world of intentional, mindful eating. Taking bitters before meals is an ritual of tuning into your body’s needs, preparing for the nourishment and energy food provides. In many traditions, the bitter taste is associated with grounding, detoxification, and fostering a deeper connection with the earth.
As we engage with the lore of digestive fire, remember that this ancient wisdom isn't just a relic of the past. By rekindling this connection to bitter herbs, we invite an awareness of our digestive health that transcends mere function and becomes part of a meaningful, healthful lifestyle.
So, let these bitters awaken not just your digestive fire but also a little spark of the magic within you, rooted in nature and mindful of every meal shared with friends, family, and the earth itself.
With love,
Sia
