Essential Equipment
Part of Pharmacy and Apothecary
The tools required to operate a functional apothecary — measuring, grinding, extracting, and storing medicinal preparations.
Why This Matters
A skilled pharmacist with no tools is nearly helpless. The tools of the apothecary are not luxuries — they are the mechanisms that convert raw plant material into precise, reliable doses of medicine. Without a scale, you cannot dose accurately. Without a mortar and pestle, you cannot reduce hard materials to bioavailable powder. Without proper storage vessels, your preparations degrade in days.
The good news is that most pharmaceutical equipment is simple, durable, and can be made or improvised. Apothecaries operated effectively for thousands of years before stainless steel and laboratory glass existed. Understanding what each tool does and why it matters allows you to substitute, improvise, or manufacture locally when necessary.
Equipment also sets up the workflow of your apothecary. Well-organized tools mean preparations are made efficiently, with fewer errors. A chaotic workspace is a dangerous workspace — a mislabeled vessel or a contaminated pestle can turn medicine into poison.
Measuring Equipment
Balance scale: The most critical piece of equipment. For medicine, you need to measure in grams and ideally in fractions of a gram. A simple two-pan balance with known reference weights works perfectly. Make reference weights from stones, metal pieces, or anything that can be verified against a known standard. One reference weight of 1 gram (the weight of a paper clip, roughly) and a set of 1, 2, 5, and 10 gram weights covers most needs.
Improvised scales can be made from a rigid horizontal beam balanced on a central pivot, with pans suspended from each end. The challenge is the pivot — it must allow the beam to move freely with very small weight differences. A needle or nail through the beam, resting on two hard supports, works reasonably well.
Volumetric containers: Marked containers for measuring liquids. Calibrate with water — weigh out 10 grams of water (which equals 10 mL) and mark your container at that level. Add more 10 mL increments until you have a container marked in useful graduations.
Standardized spoons: Keep a dedicated set of spoons used only for measuring medicines. Measure each spoon with water and mark its capacity. A teaspoon is approximately 5 mL; a tablespoon approximately 15 mL — but verify yours.
Thermometer: Optional but useful for distillation and fermentation work. If unavailable, learn the visual temperature cues — small bubbles at the bottom of a pan (70°C), simmering with gentle surface disturbance (80-90°C), rolling boil (100°C), the touch test for body temperature (should feel neutral on the inside of your wrist, not hot or cold).
Grinding and Processing
Mortar and pestle: The most fundamental apothecary tool. Stone is best — heavy, non-reactive, easy to clean. Ceramic works. Wood absorbs residues and is harder to clean, but acceptable for single-herb work. Size matters: a mortar with a 15-20 cm diameter bowl can grind meaningful quantities. Smaller mortars are for fine work and small quantities.
Keep multiple mortars or clean between uses. Residue from a previous preparation can contaminate the next, leading to unpredictable dosing.
Technique: work in small batches for fine powders. Press down and rotate, do not just strike. For very hard materials like seeds, crack them first with a heavier tool before grinding.
Herb cutting board and knife: A dedicated cutting surface and sharp knife for chopping fresh plant material before extraction. Keep these separate from food preparation surfaces to prevent contamination in both directions.
Sieves and strainers: For removing plant solids from liquid extracts. Multiple mesh sizes are useful: coarse (like a colander) for large pieces, fine cloth (muslin or tightly woven linen) for fine particles. A jelly bag — a cloth bag that liquid is poured through and squeezed — extracts maximum liquid from plant solids.
Pressing equipment: When making expressed juices or extracting maximum liquid from plant material, you need to press the solid. A simple fruit press, or even a potato ricer, works. For small quantities, squeeze through cloth by hand.
Heating Equipment
Cooking fire with good heat control: Most pharmaceutical preparations require heat. You need a fire or stove that can maintain a gentle simmer reliably — not just boil everything. Three-stone fires with adjustable fuel work. A clay brazier offers better control than an open fire.
Double boiler: Melting beeswax and fats for salves and ointments requires gentle, even heat to avoid burning. A double boiler — a pot set over a pot of simmering water — distributes heat gently. Can be improvised from any two containers where the smaller sits inside the larger without touching the bottom.
Still or distillation apparatus: For making distilled water, tinctures, or essential oils. At minimum, a pot with a tight-fitting lid, a tube to carry vapor away, and a cold water bath to condense the vapor. Clay pots with fitted lids were used for distillation for thousands of years. See Steam Distillation for detailed construction.
Storage Vessels
Glass bottles with stoppers: Best for tinctures, syrups, and liquid preparations. Glass is non-reactive and non-absorptive. If glass is unavailable, use ceramic or glazed clay containers. Unglazed clay is porous and will absorb liquids. Metal containers may react with acidic preparations.
Wide-mouth jars with lids: For dry herb storage and powders. Airtight is critical — moisture degrades dried herbs rapidly.
Labeling system: Every container must be labeled immediately upon filling. Use waterproof ink, or score information into clay labels before firing. Minimum information on any label: name of contents, date made, and concentration.
Dark storage: Many preparations degrade when exposed to light. Store in dark bottles, wrap in cloth, or store in a dark cabinet. A simple wooden box or cupboard in a cool room dramatically extends shelf life of most preparations.
Cleaning and Sterilization
Boiling water: The primary sterilization method. Boil all preparation equipment before use for medicines that will be applied to wounds or eyes. A large pot kept exclusively for sterilization is worth maintaining.
Alcohol: If available, alcohol rinses equipment between uses when boiling is impractical. 70% alcohol is more effective than pure alcohol for surface sterilization.
Dedicated apothecary surfaces: Do not prepare medicines on surfaces also used for raw food preparation. Cross-contamination of plant resins into food is a minor issue; contamination of medicines with food pathogens is a serious one.
Minimal Starting Kit
If building from nothing, prioritize in this order:
- Stone mortar and pestle
- Balance scale with reference weights
- Collection of glass or ceramic storage vessels with stoppers
- Fine cloth for straining (at least 2 meters of muslin)
- Double boiler setup
- Standardized measuring spoons
- Record book and permanent ink
With these seven items, you can prepare the majority of pharmaceutical dosage forms described in the pharmacopoeia.
