Studies conducted on the medical properties of hops have found that it has similar medical properties to Valerian, due to the antibacterial, anti-fungal and antioxidant properties found in both. Hops and valerian may both provide the following medical benefits:

Anxiolytic properties.

Treatment for insomnia.

Treatment for digestive problems.

Reducing menopausal symptoms.

Hops Strobiles

Humulus lupulus

Area of origin: Germany

Hops strobiles are the cone shaped flowers of the humulus lupulus vine. Most commonly used for its bittering, flavouring and stabilizing properties in beer, hops are characterised by its floral, citrus, or earthy aroma and flavour. Hop cultivation is extremely popular and as a result there is a wide variety of hops species, each with a unique combination of aroma, flavour and bitterness. Hops are also used in many traditional medicines and for flavouring for soft drinks, herbal teas and tea blends.

plant name

Hop, hop (English)

International Latin denomination

Humulus lupulus L.

botanical family

Cannabaceae

Description and habitat

• Perennial dioecious lianoid herbaceous plant, with opposite lobed leaves, ovoid yellow-greenish female flowers grouped in clusters, formed of membranous scales (bracts and bracteoles) which bear lupulin (oleoresin) glands in red-orange grains

History and tradition

• Cultivated for the production of beer from the 8th century in Germany
• Produced by hop fields in many countries with a temperate climate (Alsace, temperate Europe)

Parts used

• Dried female inflorescence (called “cone” or strobile)

Dosage forms available

• Mother tincture of female inflorescence (cone)
• Female inflorescence EPS (cone)

Usual dosages

Composition

Main components of the plant

• Flavonoids  :
  • Rutoside , quercitroside , astragaloside
  • Flavanones  : hopein (= 8-prenyl-naringenin ), 6-prenylnaringenin , 3'-geranylchalconaringenin , 6-geranylnaringenin , 8-geranylnaringenin , 4'-O:-methyl-3'-prenylchalconaringenin , 6,8-diprenylnaringenin
  • Isoprenylated chalcones : xanthohumol and isoxanthohumol
• Essential oil (0.3 to 1%): beta-myrcene , humulene (= alpha-caryophyllene ), caryophyllene
• Oleo-resins or prenylated derivatives of a 1-acyl- phloroglucinol  : lupulone , humulone (15 to 30%) responsible for the bitterness

Main components of buds or young shoots

Main components of essential oil

• Monoterpene  : beta-myrcene (acyclic, 3) 50%
• Sesquiterpenes  : beta-caryophyllene , alpha-cadinene
• Humulene (= alpha-caryophyllene )

Properties

Plant properties

• Sedative, antibacterial activity
• Analgesic, effect mediated by opioid receptors, but not by serotonergic or alpha(2)-adrenergic receptors [1]
• Powerfully estrogenic [2] by various polyphenols  : isoflavones , chalcones (including xanthohumol ), prenylated flavones including especially 8-prenyl-naringenin (= hopein ): at a dose of 30mg/Kg body weight in rats for 14 days, l enlargement of the uterus is the same as that obtained with 0.01mg/Kg of estradiol (3000 times lower activity in molecular weight ratio) [3] , [4]
• The activity is identical at the level of the alpha and beta estrogen receptors [5]
• Isoxanthohumol , weakly phytoestrogenic can be bioactivated by 8-prenyl-naringenin [6] , [7] , with intervention of the saprophytic flora (microbiota) [8]
• 8- prenyl -naringenin inhibits angiogenesis in vitro and in vivo [9]
• Effective on hot flushes with 8-prenyl-naringenin at a dose of 400 µg/kg [10] , and on menopausal discomfort [11] , [12]

Bud properties

Properties of essential oil

Directions

Indications of the whole plant (phytotherapy)

• Disorders of the menopause, hot flashes, hops would decrease the body temperature [13]
• Instability, hyperexcitability, insomnia of nervous origin and states of stress
• Sleep onset insomnia during menopause
• Symptomatic treatment of neurotonic states in adults and children, especially in cases of minor sleep disorders
• appetite stimulation
• female hirsutism (?)

Indications of the bud (gemmotherapy)

Specific indications of essential oil (aromatherapy)

Known or suspected mode of action

• Methylbutenol formed from humulone and lupulone can be considered as one of the active ingredients, its content increases during storage
• Hopein (= 8- prenyl -naringenin ) is potently estrogenic, and at a dose of 30 mg/Kg of body weight in rats for 14 days, the increase in the uterus is the same as that obtained with 0.01 mg/ Kg of estradiol (source AFSSAPS)

Usual formulations

• Classic galactogenic herbal tea formula:
  • Angelica Angelica archangelica seeds...30 grams
  • Green anise Pimpinella anisum seeds...30 grams
  • Fennel Foeniculum vulgare seeds ... 30 grams
  • Caraway Carum caraway seeds...60 grams
  • Hops Humulus lupulus cones ... 20 grams
  • One teaspoon per cup. Boil 2 to 3 minutes, infuse 10 minutes. Drink 2 to 3 cups a day

Regulations

• French Pharmacopoeia list A (female inflorescence called "hop cone")

• Contraindicated in mastosis and history of breast cancer, hormone-dependent cancers
