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
