Identification
Morphology
Humulus scandens is a herbaceous plant characterized by its distinctive climbing nature. This species possesses an obligatory climbing habit, meaning it relies on external structures to ascend toward the light. Depending on its environment, the plant typically reaches a height of at least 2 meters. Under optimal conditions, it can continue its upward growth to reach a maximum height of 6 meters.

Conditions
Humulus scandens is not explicitly mentioned in the provided abstract as having larvicidal activity. The research focuses on 56 different Euro-Asiatic plant species, but it specifically identifies Humulus japonicus rather than Humulus scandens. While the study confirms that all tested extracts showed larvicidal effects against Culex quinquefasciatus at a 500 ppm dose, this specific species was not listed among the top performers. Consequently, the data provided does not offer a direct measurement of the effectiveness for Humulus scandens. Therefore, no specific lethal dose or ranking can be established for this plant based on the text.
Preparations
Parts used
Humulus scandens is a plant species that can be characterized through the detailed study of its various anatomical structures. Specifically, the stem and leaf serve as the primary components used for pharmacognostical identification. Researchers focus on the histological and powder characteristics of these parts to ensure accurate medicinal classification. In particular, the unique microscopical features of the leaf provide a critical basis for botanical identification. By analyzing both the stem and leaf, scientists can establish a reliable profile for this medicinal material.
