One of homeopathy's greatest strengths is in acute, first-aid situations. While constitutional treatment for chronic conditions requires professional guidance, acute prescribing — selecting a remedy for a specific, time-limited situation — is something anyone can learn. A well-stocked homeopathic first aid kit and the knowledge to use it can be genuinely useful for everyday bumps, bruises, bites, and digestive upsets.
This guide covers twelve remedies that form the backbone of a home first aid kit, with practical guidance on when to use each one, which potency to choose, and how often to dose.
Understanding Potency: 6C vs. 30C
Before we dive into the remedies, you need to understand the two potencies you'll use most often in first aid:
6C (low potency): Best for mild symptoms, gradual onset, and situations where you're not completely sure of the remedy match. Can be repeated frequently — every 15-30 minutes in acute situations. Gentle and forgiving.
30C (medium potency): Best for clear, well-matched symptom pictures and more intense acute situations. Stronger action, so dose less frequently — every 1-2 hours. This is the standard first-aid potency for most practitioners.
The golden rule of acute dosing: Give the remedy and watch. If symptoms improve, stop dosing. Repeat only when improvement stalls or symptoms return. If there's no response after 3-4 doses, the remedy is likely not the right match — reconsider your choice.
The 12 Essential Remedies
1. Arnica montana — The Trauma Remedy
Use for: Bruises, muscle soreness, blunt trauma, falls, overexertion, post-surgical recovery, shock from physical injury.
Arnica is the first remedy to reach for after any physical trauma. A 2024 systematic review published in Plants analyzed studies on both phytotherapeutic and homeopathic forms of Arnica and found evidence supporting its anti-inflammatory and tissue-healing properties, particularly in sports injuries and post-surgical contexts.
Potency: 30C for acute injuries, 6C for general muscle soreness after exercise
Dosing: 30C every 1-2 hours for acute trauma, reducing frequency as pain improves. For post-exercise soreness, 6C three times daily for 1-2 days.
Key indicators: The person says "I'm fine" when they clearly aren't. Soreness and bruising. Feeling beaten up. Worse from touch.
2. Calendula officinalis — The Wound Healer
Use for: Cuts, scrapes, abrasions, minor burns, surgical incisions, any open wound.
Calendula promotes rapid wound healing and has well-documented antimicrobial properties. It is used both internally (in pellet form) and externally (as a cream or diluted tincture for wound washing). Multiple studies have confirmed its promotion of granulation tissue formation and wound closure.
Potency: 30C internally, plus topical Calendula cream or diluted tincture on the wound
Dosing: 30C three times daily until the wound shows clear healing progress
Key indicators: Open wounds, raw surfaces, slow-healing cuts. Use after cleaning the wound thoroughly.
3. Apis mellifica — The Sting Remedy
Use for: Bee stings, wasp stings, insect bites, allergic reactions with swelling, any condition with puffiness and stinging pain that feels better from cold.
Potency: 30C for acute stings and significant swelling
Dosing: Every 15-30 minutes for the first hour, then hourly as swelling reduces
Key indicators: Red, hot, puffy swelling. Stinging, burning pain. Better from cold applications. Worse from heat and pressure. The swollen area looks shiny and tight.
Important: Apis is for mild to moderate reactions. Anaphylaxis (difficulty breathing, throat swelling, widespread hives) is a medical emergency — use an EpiPen if available and call emergency services immediately.
4. Nux vomica — The Digestive Reset
Use for: Overeating, food poisoning, hangovers, indigestion, nausea, constipation from dietary excess, stomach upset from rich or spicy food.
Potency: 30C for acute digestive upset, 6C for mild indigestion
Dosing: 30C every 2 hours for food poisoning or hangover, 6C after overeating
Key indicators: The "too much" remedy. Too much food, too much alcohol, too much stress. Irritability with digestive complaints. Nausea with an urge to vomit but difficulty doing so. Worse in the morning.
5. Hypericum perforatum — The Nerve Injury Remedy
Use for: Injuries to nerve-rich areas (fingers, toes, spine, lips, teeth), puncture wounds, shooting pains along nerve paths, dental procedures, tailbone injuries.
Potency: 30C for acute nerve pain
Dosing: Every 1-2 hours for acute nerve injury, reducing as pain subsides
Key indicators: Sharp, shooting pains radiating along a nerve. Injuries to fingertips, toes, or the coccyx. Pain seems excessive relative to the visible injury. Post-dental work pain.
6. Ledum palustre — The Puncture Wound Remedy
Use for: Puncture wounds, animal bites, insect bites, splinter wounds, black eyes, any wound that feels better from cold application.
Potency: 30C for puncture wounds and bites
Dosing: Every 2-4 hours for the first day, then three times daily for 2-3 days
Key indicators: The wound feels cold to the touch but the person doesn't want warmth on it. Puncture-type injuries (stepping on a nail, thorns, animal teeth). Black eyes that feel better from cold.
7. Rhus toxicodendron — The Stiffness Remedy
Use for: Sprains, strains, stiff joints, back pain, cold sores, skin rashes with small blisters, conditions that are worse with initial movement but improve with continued motion.
Potency: 30C for acute sprains and back pain
Dosing: Every 2-4 hours in acute situations
Key indicators: The signature "rusty gate" pattern: stiffness and pain that is worst on first movement, improves as the person moves and warms up, then worsens again from prolonged exertion. Restlessness. Worse in cold, damp weather.
8. Belladonna — The Sudden Onset Remedy
Use for: High fevers that come on suddenly, throbbing headaches, earaches, sunstroke, any intense condition that appears rapidly with heat and redness.
Potency: 30C for acute fevers and headaches
Dosing: Every 30-60 minutes during intense symptoms, reducing as the condition eases
Key indicators: Sudden, violent onset. Intense heat radiating from the body. Red, flushed face. Throbbing pain. Dilated pupils. The person may be sensitive to light, noise, and jarring motion.
9. Chamomilla — The Teething and Irritability Remedy
Use for: Teething pain in children, earaches (especially in children), toothache, colic, any painful condition accompanied by extreme irritability and anger.
Potency: 30C for acute teething and earache pain
Dosing: Every 30-60 minutes for intense distress, reducing as the child calms
Key indicators: Extreme irritability — nothing satisfies the person. One cheek red, the other pale. The child wants to be carried constantly. Pain seems unbearable and disproportionate. Better from being rocked or carried.
10. Aconitum napellus — The Shock and Fright Remedy
Use for: Panic attacks, shock from a frightening experience, early stages of colds and fevers (especially after exposure to cold wind), anxiety with restlessness.
Potency: 30C for acute panic, shock, or early-stage fever
Dosing: Every 15-30 minutes for panic or shock, hourly for early cold/fever symptoms
Key indicators: Sudden onset after fright or cold exposure. Intense anxiety, even fear of death. Restlessness. Dry, hot skin. Symptoms come on like a storm — fast and furious.
11. Arsenicum album — The Food Poisoning Remedy
Use for: Food poisoning with simultaneous vomiting and diarrhea, stomach flu, restlessness with exhaustion, burning pains relieved by warmth.
Potency: 30C for acute gastroenteritis
Dosing: Every 1-2 hours during active symptoms
Key indicators: Vomiting and diarrhea at the same time. Burning pains in the stomach that feel better from warm drinks. Extreme restlessness despite being exhausted. Anxiety about health. Worse between midnight and 2 AM. Thirsty for small, frequent sips.
12. Ruta graveolens — The Tendon and Bone Remedy
Use for: Injuries to tendons, ligaments, and the periosteum (bone covering). Eye strain, repetitive strain injuries, bruised bones, shin splints.
Potency: 30C for acute tendon/ligament injuries
Dosing: Three times daily for 5-7 days
Key indicators: Injuries where bones feel bruised. Tendon and ligament injuries that don't respond to Arnica or Rhus tox. Eye strain from prolonged screen use. Feeling of weakness in the affected area.
How to Stock Your Kit
You can purchase individual remedies or pre-made kits. For a home first aid kit, stock all twelve in 30C potency (the most versatile for acute prescribing). Add 6C potencies of Arnica and Nux vomica for milder situations.
Storage tips:
Keep remedies in a cool, dry place away from strong aromas (essential oils, camphor, mint)
Homeopathic pellets have a very long shelf life when stored properly — years or decades
Handle pellets by tapping them into the cap and then into the mouth; avoid touching them with your fingers
Take remedies 15-20 minutes away from food, drink, or strong flavors
When to Seek Professional Help
Homeopathic first aid is designed for acute, self-limiting situations. Seek professional medical attention for:
Any injury involving significant bleeding, head trauma, possible fractures, or loss of consciousness
Allergic reactions involving breathing difficulty or throat swelling
Symptoms that worsen despite treatment or persist beyond 48-72 hours
High fevers (above 103°F in adults, above 100.4°F in infants under 3 months)
Any situation where you feel uncertain about the severity
For chronic conditions or constitutional treatment, consult a qualified homeopath. Explore our Homeopathy Library for in-depth remedy profiles, or use the Homeopathic Remedy Finder to match symptoms to remedies.
