What are the medicinal constituents this herb?

The most important healing constituents of Humulus lupulus are humulone, lupulone, xanthohumol, 8-prenylnaringenin, and caryophyllene.

Humulone and lupulone, two sesquiterpene acids, exhibit antimicrobial and anti-inflammatory properties, contributing to the plant's potential in wound healing and antimicrobial therapy. Xanthohumol, a prenylated flavonoid, has been shown to possess antioxidant, anti-inflammatory, and anti-cancer properties, highlighting its potential in protecting against oxidative stress and cell damage. 8-prenylnaringenin, a prenylated flavonoid, has been found to have estrogenic activity, making it a potential therapeutic agent for menopausal symptoms and osteoporosis.

Caryophyllene, a sesquiterpene, exhibits anti-inflammatory and analgesic properties, further supporting the plant's potential in pain management and inflammation reduction.

What are the main herbal preparations this herb?

The main herbal preparations of Humulus lupulus are hop oil, a volatile oil extracted from the cone's lupulin glands, containing alpha acids, responsible for the bitter flavor and preservative properties; hop extract, a concentrated form of hop cones, used in brewing and as a dietary supplement; hop tea, an infusion made from dried hop cones, traditionally used to aid sleep; lupulin tea, a tea prepared from the lupulin glands, rich in sesquiterpenes and humulone, compounds with antimicrobial and anti-inflammatory properties; hop tincture, a concentrated liquid extract of hop cones, used in herbal medicine for its sedative and anti-anxiety effects.

What are the possible side effects of using this herb improperly?

The possible side effects of using Humulus lupulus improperly include interactions with medications such as blood thinners, as it can inhibit the CYP3A4 enzyme, increasing the risk of bleeding and bruising.

Additionally, consuming excessive amounts can induce vomiting due to its bitter compounds, such as humulone and lupulone, which can irritate the stomach lining. Furthermore, improper use can cause dizziness and lightheadedness due to its vasodilatory properties, which can lower blood pressure and reduce blood flow to the brain. Developing allergic reactions to Humulus lupulus is also a possibility, as it contains terpenoids and flavonoids that can trigger an immune response, resulting in symptoms such as hives, itching, and difficulty breathing.

Lastly, consuming large quantities can cause diarrhea due to its saponin content, which can disrupt gut motility and increase water loss in the stool.
