Identification
Morphology
Crotalaria spectabilis is a self-supporting herb that establishes a sturdy presence in its natural habitat. This plant typically reaches a height of at least 1 meter, though it often grows much taller. While it can reach a minimum of 1.65 meters in certain conditions, its full development is impressive. Ultimately, the species can achieve a maximum height of up to 2 meters. This consistent growth pattern makes it a distinct feature within its ecosystem.

Biological Activities
Compounds
Conditions
Crotalaria spectabilis induces pulmonary hypertension through significant structural changes in the pulmonary arterial circulation. This process includes increased medial and adventitial thickness alongside a reduction in the number of peripheral arteries. Furthermore, ingestion of the plant induces hyperplasia and hypertrophy of pulmonary arterial cells at both pre- and intra-acinar levels. These physiological alterations collectively result in the characteristic structural changes associated with pulmonary hypertension. The resulting vascular damage and subsequent cellular responses represent an adaptation to the induced hypertensive state.
Preparations
Parts used
Crotalaria spectabilis seeds serve as a significant source of toxins that can trigger severe physiological changes in consuming animals. When these seeds are ingested, they induce structural alterations in the pulmonary arterial circulation, leading to the development of pulmonary hypertension. Research indicates that this condition is characterized by increased thickness in the medial and adventitial layers of the arteries. Furthermore, the consumption of the plant causes the unexpected appearance of muscle in smaller arteries that are normally non-muscularized. Ultimately, the ingestion of these specific plant parts drives cellular hyperplasia and hypertrophy within the pulmonary system.
