Herbal Actions

Horseradish is traditionally associated with the following actions:

• Circulatory stimulant – encourages blood flow and warmth
• Respiratory stimulant – supports clearance of congestion
• Expectorant – helps loosen and move thick secretions
• Antimicrobial support – traditionally used to discourage unwanted microbes
• Digestive stimulant – promotes digestive fire and appetite

These actions describe traditional functional use rather than medical treatment.

Practical Uses

In Western herbal practice, horseradish is typically used short term, especially for respiratory congestion, sinus pressure, and cold-related sluggishness. Herbalists value it for its immediacy and intensity, often combining it with gentler herbs to balance its stimulating nature. It is rarely used as a standalone long-term tonic.

Product Forms

Horseradish is available in several preparations:

• Fresh root – grated or macerated for immediate use
• Tinctures – alcohol extracts of fresh root
• Syrups – often combined with honey for respiratory support
• Vinegar extracts – traditional food-medicine preparations
• Capsules – powdered root, less common

Fresh root preparations are considered the most active.

Traditional Herbal Recipes

1. Fresh Horseradish Root Tincture
   Prepared from freshly grated root for circulatory and respiratory stimulation.
2. Horseradish & Honey Syrup
   Traditionally used to support sinus and chest clarity.
3. Warming Vinegar Extract
   Used in small amounts to stimulate digestion and circulation.
4. Respiratory Support Blend
   Horseradish combined with gentler expectorant herbs.

Parts Used

• Root, harvested fresh for highest activity

Usage Forms & Shelf Life

Internal vs external use:
Primarily internal; occasional external use in poultices.

Common preparations:
Fresh root, tinctures, syrups, vinegars

Shelf-life ranges:

• Fresh root: several weeks refrigerated
• Tinctures: 3–5 years
• Syrups: 3–6 months refrigerated

Safety & Considerations and Dosage Guidelines

Horseradish is traditionally used in small amounts and for short durations. Herbalists emphasize moderation due to its strong stimulating nature. It is typically avoided for continuous daily use.

Side Effects & Contraindications

Horseradish may cause irritation to sensitive digestive or respiratory tissues if used excessively. It is traditionally avoided in cases of active inflammation, ulcers, or heat-dominant conditions. External contact may irritate skin.

Active Constituents

Glucosinolates & Isothiocyanates

• Compounds: sinigrin, allyl isothiocyanate
• Traditional role: associated with antimicrobial, circulatory, and respiratory stimulation
• Best extraction: fresh root tincture or vinegar
• Quantitative data: sinigrin content varies widely but can reach 1–2% of fresh root weight
  National Center for Biotechnology Information

Volatile Oils

• Traditional role: pungent aroma linked to sinus-clearing action
• Best extraction: fresh preparations

Flavonoids

• Traditional role: antioxidant support
• Best extraction: alcohol and vinegar

How It Works

Traditionally, horseradish is understood to work by rapidly increasing circulation and stimulating mucus movement, helping clear congestion and restore flow. Modern research supports its antimicrobial and circulatory effects, aligning with its historical use for short-term respiratory and immune support

Processing Cautions

Horseradish loses potency quickly once dried. Fresh processing is essential to preserve volatile isothiocyanates. Grating releases active compounds rapidly and should be done in well-ventilated areas.
