The genus Aconitum worldwide is notorious for complex patterns of morphologic intergradation that blur the lines between taxa. Aconites from different regions may be morphologically distinct but connected by a series of intermediate races[]. There have been huge differences of opinion between botanists as to how to define a species in this genus, with the Flora of N. America recognizing around 100 species worlwide[], whilst the Flora of China recognizes 211 species in China alone and around 400 species worldwide[]. We are following the proposed treatment in the 'World Checklist of Selected Plant Families', which is still under review, but currently (2016) recognizes about 320 distinct species (391 including hybrids and infraspecific forms) and over 1,000 synonyms[].

Common Name: Wild Monkshood

General Information

Aconitum uncinatum is herbaceous perennial plant producing a stem 30 - 250cm tall that can be erect, scrambling or twining into other vegetation. The stem grows from an underground tuber[], the parent tuber producing several (ca. 5) daughter tubers separated from the parent by connecting rhizomes 5-30mm long[].
The plant is harvested from the wild for local medicinal use.

Known Hazards

The whole plant is highly toxic - simple skin contact has caused numbness in some people[].
The aconites have been of interest since ancient times because they contain diterpene alkaloids that range from relatively nontoxic to deadly poisonous. In various parts of the world they have been used medicinally and as a source of poisons throughout history. The use of Aconitum alkaloids in modern Western medicine was largely discontinued by the late 1930's and early 1940's, though the roots are still widely used in traditional medicine, especially in Asia[, ].

Medicinal

The dried root is alterative, anaesthetic, antiarthritic, deobstruent, diaphoretic, diuretic, sedative, stimulant[].
A tincture is used as an external anaesthetic[].
The plant is harvested as soon as it dies down in the autumn.
This is a very poisonous plant and should only be used with extreme caution and under the supervision of a qualified practitioner.

Propagation

Seed - best sown as soon as it is ripe in a cold frame[]. The seed can be stratified and sown in spring but will then be slow to germinate[]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter. Plant them out in late spring or early summer.
Division - best done in spring but it can also be done in autumn[, ]. Another report says that division is best carried out in the autumn or late winter because the plants come into growth very early in the year[].
