Botanical Overview
Larkspur (Consolida ajacis) is a species in the Ranunculaceae family. The buttercup family (Ranunculaceae) includes herbs with alternate or basal leaves and showy flowers with numerous stamens and pistils. Many species contain protoanemonin and other acrid compounds that cause skin irritation. Despite their toxicity, several species have been used in traditional medicine for pain and inflammation. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 23 compounds in this species, suggesting potential medicinal value.
General Description
It is widespread in other areas, including much of North America, where it is an introduced species. It is frequently grown in gardens as an ornamental for its spikes of blue, pink or white flowers. It may reach a meter in height. Since the aerial parts and seeds of C. ajacis have been found to contain diterpenoid alkaloids (see chemical constituents below), including the highly toxic methyllycaconitine, the plants should be considered as poisonous.
Family Context
The Ranunculaceae family is widely distributed in temperate regions. Notable medicinal members include:
- Black Cumin — 29 documented uses
- Goldenseal — 29 documented uses
- Bugbane — 28 documented uses
- Black Cohosh — 24 documented uses
Geographic Distribution
Larkspur has been recorded in 10 countries and territories worldwide, including Austria, Belgium, Switzerland, Germany, Spain, and others.
Active Compounds
Phytochemical research has identified 23 compounds in this species, including a diverse array of phytochemical classes (see the Complete Chemical Inventory below for the full list).
The identified compounds include the following categories:
- Alkaloid: nitrogenous compounds with diverse pharmacological activities
Research Status
Although this species has documented phytochemical constituents, its ethnobotanical and clinical documentation remains incomplete. Additional phytochemical investigation could identify novel bioactive compounds in this plant.
