Ranunculaceae (Buttercup Family)
- Large family of herbaceous and woody plants.
- Perianth and stamens have many free members.
- Acyclic arrangement of pistils.
- Many ovaries in one flower.
- 50 genera and 1800 species.

- Perennial, up to 50-200 cm tall.
- Has two tubers underground.
- One tuber provides the current year's plant, the other provides the following year's.
- Tubers contain Tubera Aconiti T.K. (aconite tuber).
- Contains 0.5-1.5% alkaloids, primarily aconitine.
- Used as a pain reliever, especially for nervous trigeminus neuralgia, and as a cough sedative.
- Other species exist: A. orientale, A. nasutum, and A. cochleare, also containing alkaloids.
Delphinium staphisagria (Licebane)
- Grows in a Mediterranean climate.
- Used in veterinary medicine to eliminate parasites.
- Contains staphisagrin alkaloid.
- Seeds are extremely poisonous.
Hydrastis canadensis (Goldenseal)
- Perennial herbaceous plant (30-40 cm).
- Found in North America.
- Short rhizome and numerous roots and just 2 leaves.
- Single flower.
- Also a poisonous plant.
- Roots and rhizomes yield Rhizoma Hydrastis T.K.
- Contains alkaloids like hydrastine and berberine.
- Used as a hemostatic (stops bleeding) in uterine hemorrhages.
Cimicifuga racemosa (Black Cohosh)
- Perennial herbaceous plant (up to 1-2 m).
- Native to North America.
- Roots/rhizomes produce Rhizoma Cimicifugae racemosae (dark brown).
- Contains acteine and cimicifugoside (triterpene glycosides) as active constituents.
- Used in menopause complications like hot flashes and sweating and also in sleep disorders and rheumatism.
Coptis chinensis (Chinese Gold Thread)
- Grows in the Far East (China and Japan).
- Rhizomes have a bitter taste.
- The drug Rhizoma Coptidis is used in gastrointestinal disorders, as an antibiotic, and antibacterial agent.
- Contains berberine, protoberberine, and palmatine alkaloids.
- Also protects heart muscle and decreases blood sugar.
Helleborus niger (Black Hellebore)
- Found in European forests.
- Roots/rhizomes yield Rhizoma Hellebori nigri, containing hellebroside glycoside.
- Has cardiotonic activity (increases heart muscle contractions).
Helleborus orientalis (Oriental Hellebore)
- Grows in Northern Anatolia.
- The drug Radix Hellebori (root) is used in chest diseases of cattle.
- Contains cardiotonic heterosides (glycosides).
Adonis vernalis (False Hellebore)
- Annual plant with yellow or red flowers.
- Found in Europe.
- Aerial parts (Herba Adonidis) contain a cardiotonic heteroside (adonitoxoside).
- Also used as diuretic.
- Other species include Adonis aestivalis and Adonis flammea.
Paonia officinalis (Peony)
- Roots (Radix Paeoniae) contain the heteroside peonol.
- Has astringent and antispasmodic activities.
- Used as a sedative in epilepsy and whooping cough.
Nigella sativa (Black Sesame)
- Cultivated in Central and West Anatolia.
- Annual plant.
- The oil (Oleum Nigellae) contains thymoquinone.
