The 1864 preparations contain either crude opium or its aqueous Extractum Opii; those quantities must be distinguished from a quantity of isolated morphine. The following are the officinal opium preparations. Ratios for solids mean the mass fraction in the compounded preparation; liquid strengths specify mass per volume or the actual ingredients used.
- Emplastrum Opii: powdered opium in resin plaster: 1 in 10.
- Enema Opii: opium tincture 30 minims with starch decoction 2 fluid ounces. Thus the tincture is 1 volume to 32 volumes of vehicle, before mixing.
- Extractum Opii: aqueous solvent extraction of 1 avoirdupois pound of sliced opium with 6 Imperial pints of distilled water, in three successive portions, followed by evaporation. The prescribed starting quantities do not impose a fixed yield or a universal crude-drug-to-extract potency ratio.
- Extractum Opii Liquidum: Extractum Opii 1 avoirdupois ounce, distilled water 17 fluid ounces, rectified spirit 3 fluid ounces: 1 ounce of extract to the pint of liquid ingredients.
- Linimentum Opii: equal volumes of opium tincture and soap liniment: half the tincture's nominal opium strength.
- Pilula Opii: powdered opium with hard soap: 1 in 5 of the nominal pill ingredients.
- Pilula Plumbi cum Opio: powdered opium with lead acetate and confection of roses: 1 in 8.
- Pulvis Cretae Aromaticus cum Opio: powdered opium with aromatic chalk powder: 1 in 40.
- Pulvis Ipecacuanhae cum Opio: powdered opium with ipecacuanha and potassium sulfate: 1 in 10.
- Pulvis Kino cum Opio: powdered opium with kino and cinnamon: 1 in 20.

- Tinctura Camphorae cum Opio: opium 40 grains to 1 Imperial pint of proof spirit, with benzoic acid, camphor and anise oil: 2 grains of opium per fluid ounce.
- Opium tincture, Tinctura Opii: powdered opium 1½ avoirdupois ounces to 1 Imperial pint of proof spirit. Nominally this is 32.8125 grains per fluid ounce, or approximately 1 grain per 14.63 minims.
- Trochisci Opii: 72 grains of Extractum Opii in 720 lozenges: one tenth of a grain of extract per lozenge.
- Unguentum Gallae cum Opio: powdered opium 32 grains added to 1 avoirdupois ounce of gall ointment. The actual nominal total is grains, giving 32/469.5 by mass, approximately 1 in 14.67; “32 grains to the ounce of ointment taken” is not 32 grains per final ounce.
- Vinum Opii: powdered opium 1½ avoirdupois ounces, sherry 1 Imperial pint: the tincture's nominal opium proportion, in a different solvent. This formula uses crude opium, not Extractum Opii.

The arithmetic uses the new avoirdupois ounce of 437.5 grains, not the old apothecaries' ounce of 480 grains. These are historical formulation proportions, not modern assays of morphine delivered after solvent extraction. Confectio Opii was omitted in 1864, and this edition's Vinum Opii contains no spices. The separate morphine hydrochloride preparations—Liquor Morphiae Hydrochloratis, Suppositoria Morphiae, Trochisci Morphiae, and Trochisci Morphiae et Ipecacuanhae—contain an isolated alkaloid salt rather than crude opium.

The required sequence is fresh flowers; sliced and dried bulb; unexpanded petals; heartwood; seeds; expressed seed fat; expressed seed oil; and fresh and dried root. The plant organ, its state, and the actual official material must all be specified.
- Sambucus nigra: fresh flowers. The official article is Sambuci flores, elder flowers, gathered from the native plant. The flower stalks are separated when making elder-flower water; the preparation also allows an equivalent quantity of flowers preserved fresh with common salt. Neither elder berries nor elder bark answers the botanical part asked here.[ref]British Pharmacopoeia by the General Medical Council (1867). “Sambuci flores”, p. 274; “Aqua sambuci”, p. 45
- Squill: the sliced and dried bulb. The historical botanical source is Urginea scilla, also identified there as Scilla maritima. The medicinal slices consist of the fleshy bulb scales; this is an underground shoot structure, not a root. The official article is Scilla.[ref]British Pharmacopoeia by the General Medical Council (1867). “Scilla”, pp. 279–280
- Rosa gallica: the fresh and dried unexpanded petals. These are Rosæ gallicæ petala, the red-rose material. “Unexpanded” refers to collection before the flower has opened fully. The petals must be distinguished from the rose hip used for a different official preparation.[ref]British Pharmacopoeia by the General Medical Council (1867). “Rosæ gallicæ petala”, red-rose monograph
- Pterocarpus santalinus: the sliced or rasped heartwood. This is Pterocarpi lignum, red sandalwood. The answer is the wood, rather than bark or the exudate known as kino. Botanical relationship between two medicinal materials does not make their official definitions interchangeable.[ref]British Pharmacopoeia by the General Medical Council (1867). “Pterocarpi lignum”, p. 261
- Physostigma venenosum: the seed. Physostigmatis faba, the Calabar bean, is botanically a seed, not the entire pod. Its two large cotyledons lie inside a hard seed coat. The official alcoholic extract is made from the powdered seed.[ref]British Pharmacopoeia by the General Medical Council (1867). “Physostigmatis faba”, pp. 233–234; “Extractum physostigmatis”, p. 126
- Theobroma cacao: the concrete oil obtained by expression and heat from the ground seeds. The official article is Oleum theobromæ, cocoa butter. Naming the seed gives its source organ, but omits the important fact that the official pharmaceutical material is the separated fat. It is distinct from coconut oil.[ref]British Pharmacopoeia by the General Medical Council (1867). “Oleum theobromæ”, p. 229
- Croton tiglium: the oil expressed from the seeds. The official material is Oleum crotonis, croton oil, rather than the whole plant or an unspecified leaf preparation. The seeds are its source; the expressed oil is the article used in the official formulations.[ref]British Pharmacopoeia by the General Medical Council (1867). “Oleum crotonis”, p. 222
- Taraxacum officinale: the fresh and dried root. The official article is Taraxaci radix, dandelion root, called Taraxacum dens leonis in the 1867 standard, gathered between September and February from British meadows and pastures. The collection season and fresh/dried distinction belong to the historical standard; the answer is not the leaves or flowers.[ref]British Pharmacopoeia by the General Medical Council (1867). “Taraxaci radix”, p. 317
The names in the paper sometimes use the shorter terminology of the first British Pharmacopoeia, whereas the 1867 edition explicitly renamed many entries to identify the medicinal organ. Its alteration list, for example, maps Sambucus to Sambuci flores, Pterocarpus to Pterocarpi lignum, and Taraxacum to Taraxaci radix.[ref]

That is a nomenclature change, not permission to choose any part of the named plant.
