What medicinal compounds this plant contains?
This plant contains the medicinal compounds cis-asarone, epifriedelanol, friedelanone, gamma-sitosterol, and linoleic acid. These specific chemical constituents contribute to the diverse pharmacological profile observed in Humulus scandens. The presence of sterols like gamma-sitosterol often relates to various biological activities within plant extracts. Additionally, the fatty acid linoleic acid and specific terpenoids such as epifriedelanol and friedelanone play roles in its chemical composition. The sesquiterpene cis-asarone is another significant component identified within its structure.
According to a study published by "Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials", seven compounds were isolated and identified from Humulus scandens. These identified compounds are friedelanone (I), cis-asarone (II), epifriedelanol (III), stigmasta-4-ene-3,6-dione (IV), gamma-sitosterol (V), n-hexadecanoic acid (VI), and linoleic acid (VII). The isolation process utilized column chromatography on silica gel and Sephadex LH-20. Identification of the structures was achieved through IR, 1H-NMR, 13C-NMR, and MS analyses. All 7 compounds were isolated from this species for the first time, and compounds I through V were obtained from this genus for the first time.
The primary medicinal compounds of this plant are shown in the list below.
- cis-asarone
- epifriedelanol
- friedelanone
- gamma-sitosterol
- linoleic acid
What health conditions is this plant used for?

What are the herbal preparations of this plant?
This plant is Humulus scandens, a climbing vine in the Cannabaceae family used to create medicinal preparations such as decoctions, infusions, and topical poultices.
These herbal remedies are traditionally prepared by steeping the leaves and stems in hot water to extract bioactive compounds. Some practitioners utilize concentrated tinctures made with alcohol to preserve the plant's properties for long-term storage. When applied externally, the crushed plant matter can serve as a soothing compress for skin irritations.
These preparations are often valued in folk medicine for their purported calming or antimicrobial effects.
What side effects this plant can have?
This plant can induce severe cellular degradation characterized by cell atrophy and a significant decrease in catalase content. These physiological disruptions lead to the progressive disappearance of organelles within the mesophyll tissue cells. As the internal structure fails, the plant causes extensive membrane permeation damage. This structural instability ultimately results in severe plasmolysis of the affected cells.
According to a study published by "Ecotoxicology and environmental safety", Humulus scandens treated with 2.5 and 5.0 mg/mL of HMB showed damage rates in membrane permeation of 74.7% and 89.1% after 4 h. Physiological changes included catalase content decreases of -18.5 and -26.5 ng/mL, superoxide dismutase decreases of -27.4 and -56.6 ng/mL, peroxidase increases of 382.0 and 880.0 ng/mL, and reactive oxygen species increases of 16.7 and 27.2 ng/mL. Additionally, malondialdehyde content rose to 8.9 and 25.2 nmol/g, while water potential values changed by 0.2 and 0.3 MPa. Photosynthetic function was impacted as the net photosynthetic rate, transpiration rate, and stomatal conductance were lower than the control by 26.6 μmol·m-2·s-1, 7.7 mmol·m-2·s-1, and 0.9 mol·m-2·s-1, respectively. Finally, the intercellular CO2 concentration in the CO2 response reached 1727.5 μmol·mol-1.
The main side effects this plant can have are shown in the list below.
- cell atrophy
- decreased catalase content
- disappearance of organelles in the mesophyll tissue cells
- membrane permeation damage
- severe plasmolysis
What herbs are paired with Humulus scandens?
This plant, Humulus scandens, pairs most effectively with aromatic herbs like peppermint, lemon balm, and lavender to balance its subtle, earthy notes.
When used in herbal infusions, the addition of minty varieties helps to brighten the somewhat muted flavor profile of the climbing hop. Lavender can be integrated to provide a floral top note that complements the plant's natural bitterness. Lemon balm serves as an excellent companion for rounding out the herbal complexity through its bright citrus undertones.
