Herbal Salve Recipe Calculator
Calculate beeswax, carrier oil, and herb infusion ratios for homemade herbal salves and balms.
A salve (also called a balm or ointment) is a semi-solid preparation made by melting beeswax into herb-infused oil. The ratio of beeswax to oil determines the firmness of the final product. Getting this ratio right is essential — too much wax creates a hard, waxy lump that does not spread, while too little produces a greasy liquid that will not stay on the skin.
Core Salve Formula
Beeswax (grams) = Infused Oil (mL) × Wax Ratio
| Consistency | Wax Ratio (g/mL) | Wax : Oil by Volume | Best For |
|---|---|---|---|
| Soft salve | 0.10–0.12 | ~1:8 | Body butter, facial balm |
| Medium salve | 0.14–0.16 | ~1:5 | All-purpose healing salve |
| Firm salve | 0.18–0.22 | ~1:4 | Lip balm, portable tins |
| Hard balm | 0.25–0.30 | ~1:3 | Solid perfume, lotion bars |
Beeswax melts at approximately 62–65°C (144–149°F). Once melted and mixed with oil, it solidifies as the mixture cools, trapping the herbal compounds in a spreadable matrix.
Carrier Oils
The carrier oil serves as the base and the solvent that extracts fat-soluble compounds from herbs during infusion:
| Oil | Shelf Life | Skin Feel | Best For |
|---|---|---|---|
| Olive oil (extra virgin) | 18–24 months | Rich, slightly heavy | General healing salves |
| Sweet almond oil | 12 months | Light, absorbs well | Facial and baby salves |
| Jojoba oil | 5+ years | Very light, non-greasy | Sensitive skin, lip balms |
| Coconut oil (fractionated) | 2+ years | Very light | Tropical feel, fast absorption |
| Avocado oil | 12 months | Rich, nourishing | Dry skin, winter balms |
| Grapeseed oil | 6–9 months | Very light | Light summer salves |
Herb-to-Oil Infusion Ratio
For the oil infusion step (done before making the salve):
Dried herbs: 1 part herb to 5 parts oil by weight (1:5) Fresh herbs: 1 part herb to 3 parts oil by weight (1:3) — higher ratio compensates for water content
Infusion methods:
- Solar infusion: Place herbs in oil in a sealed jar. Set in sunny window for 4–6 weeks. Shake daily.
- Double boiler (quick method): Heat herbs in oil at 50–60°C (120–140°F) for 2–4 hours. Do not let oil smoke or boil.
- Slow cooker: Herbs in oil on “warm” setting for 12–24 hours.
Worked Example — 200 mL Medium Healing Salve
Oil: 200 mL calendula-infused olive oil. Beeswax: 200 × 0.15 = 30 g beeswax. Essential oils (optional): 2% concentration = 200 × 0.02 = 4 mL (about 80 drops).
Melt beeswax in a double boiler. Add infused oil and stir until combined. Remove from heat. When cooled to ~50°C, add essential oils. Pour into tins or jars. Allow to cool completely (2–4 hours) before capping.
Yield: 200 mL oil + 30 g wax produces approximately 210–220 mL of finished salve (wax adds about 10% volume).
Essential Oil Safety
| Population | Max Essential Oil % | Drops per 100 mL oil |
|---|---|---|
| Adults | 2–3% | 40–60 drops |
| Children (6–12) | 1% | 20 drops |
| Children (2–6) | 0.5% | 10 drops |
| Infants (under 2) | 0.25% or NONE | 5 drops or avoid |
| Pregnant women | 1% max | 20 drops |
