Ajuga bracteosa (Ratti Buti/ Jan-e-Adam): Introduction, Scientific Classification, Geographic distribution, Morphological description, Active ingredients and Uses

Ajuga bracteosa is indigenous to the high-altitude regions of the Himalayas, primarily found in India, Pakistan, and Nepal. It thrives in alpine meadows, rocky slopes, and forest clearings at elevations ranging from 2,500 to 4,500 meters above sea level. The plant’s adaptation to harsh environmental conditions has contributed to its resilience and survival in these regions.

Aconitum chasmanthum: Introduction, Scientific Classification, Origin, Discovery, Description, Phytochemistry and Uses

As a poison
The roots of A. ferox supply the Nepalese poison called bikh, bish, or nabee. It contains large quantities of the alkaloid pseudaconitine, which is a deadly poison. The root of A. luridum, of the Himalaya, is said to be as poisonous as that of A. ferox or A. napellus.
Several species of Aconitum have been used as arrow poisons. Aconitum poisons were used by the Aleuts of Alaska’s Aleutian Islands for hunting whales. Usually, one man in a kayak armed with a poison-tipped lance would hunt the whale, paralyzing it with the poison and causing it to drown. Aconitum tipped arrows are also described in the Rig Veda.

GENETICS AND HEREDITY: Long Answer Type Question Class 10th CHAPTER 14 JKBOSE/NCERT

Analogous organs: These are structures that have similar functions and may superficially resemble each other, but they have different evolutionary origins and do not share a common ancestry.
Analogous organs arise due to convergent evolution, where different species independently evolve similar adaptations in response to similar environmental pressures.
For example, the wings of birds and insects are analogous organs as they serve the same purpose of flying but have different underlying structures and evolutionary origins.
Homologous organs: These are structures that have similar characteristics, both in terms of their structure and evolutionary origin, indicating a common ancestry.
Homologous organs share a similar basic structure but may have different functions in different species.
For example, the forelimbs of humans, bats, cats, and whales have a similar bone structure, indicating a common ancestor, but they have different functions in each species (e.g., grasping, flying, walking, swimming).
