Now more than ever, preventative health and supporting immune wellness is a major focus globally. While there are several nutritional supplements and lifestyle changes that can support immune health, there are many ingredients in your kitchen that can be of benefit.

Homemade herbal remedies and health tonics have been used for centuries to treat health conditions, prevent illness, and boost vitality. In the late 1970s, herbalist Rosemary Gladstar brought the health tonic fire cider to the mainstream for defense against colds and flu and for overall immune support.

What is Fire Cider?

Fire cider is a powerhouse remedy that is used to stimulate the body’s natural immune defenses. It consists of a base of apple cider vinegar infused with warming herbs, including garlic, ginger, onion, horseradish, and cayenne.

This wellness tonic is typically used to prevent and address the common cold, flu, sore throat, cough, sinus congestion, and digestive upset. It is especially helpful during the cold winter months but supportive throughout the year.

Benefits of Fire Cider

The ingredients of fire cider work together to reinvigorate and restore the body as follows:

1. Support immune function

Fire cider works to strengthen the immune system by stimulating the body’s natural defenses to prevent and address illness and infection.

2. Antimicrobial

Antibacterial, antiviral, and anti-fungal effects of fire cider make it a great choice for addressing a variety of infections, including the common cold and flu viruses.

3. Anti-inflammatory

Fire cider helps to reduce inflammation and regulate the immune system. It protects the body from cellular damage and assists with pain relief.

4. Improve circulation

Fire cider contains warming compounds that help to increase blood flow and strengthen the cardiovascular system improving energy and vitality.

5. Antioxidant

The herbs in fire cider are rich in antioxidant compounds that provide the ultimate defense system against oxidative stress and free radical damage to tissues.

6. Digestive aid

Fire cider is beneficial for easing digestive symptoms, including nausea, bloating, and indigestion. It contains probiotics and can be helpful when taken before meals to stimulate the production of digestive enzymes.

Healing Properties of Ingredients

1. Apple Cider Vinegar

Apple cider vinegar, especially the organic and unfiltered variety, is rich in beneficial enzymes and probiotics, making it a great digestive aid for upset stomach, nausea, bloating, and indigestion.

It has antimicrobial effects against E. coli, Staph aureus, and Candida albicans (1). Used in fire cider, it helps to extract the medicinal compounds of the herbs while also acting as a preservative.

2. Garlic

3. Onion

Onion is nutrient-dense, being a source of potassium and B vitamins, including B6 and B9. It is high in vitamin C and other antioxidants, including quercetin, which helps to reduce inflammation, regulate the immune system, and support tissue repair (4 ).

Additionally, quercetin provides allergy symptom relief by inhibiting histamine release (5). Its antimicrobial effects make it beneficial for prevention and recovery from colds and flu.

4. Ginger

Ginger is a warming herb that acts as a vasodilator to improve circulation. Ginger works as an expectorant to thin and remove mucous and congestion from the lungs, making it great for easing the common cold and flu-like symptoms.

Its main bioactive compound, gingerol, has anti-inflammatory and antioxidant properties that help in reducing nausea and indigestion (6).

5. Horseradish

Horseradish is great for alleviating sinus congestion and respiratory conditions, including the common cold, flu, and bronchitis. It helps to reduce inflammation and strengthen the immune system (7). Being rich in antioxidants, it protects the body from cellular damage caused by free radicals.

6. Cayenne

Cayenne brings the “fire” in fire cider. It has warming qualities that raise the body’s internal temperature and boost metabolism. It stimulates circulation, helping to increase blood flow and provide congestion relief making it especially useful at the onset of cold symptoms.

The bioactive compound capsaicin provides pain relief by reducing the amount of substance P known to trigger pain signals (8).

7. Honey

Honey has potent antimicrobial properties, including antibacterial and antiviral, making it highly effective for upper respiratory infections (9). Its anti-inflammatory effects help to soothe dry and inflamed tissue.

It is highly nutritious, being rich in vitamins and minerals, as well as antioxidants, including polyphenols and flavonoids (10). Honey helps to sweeten fire cider by buffering the intensity of its spiciness, making it more balanced and palatable.
