• Ginger Boosts Testosterone And More

      by Alan Gaspari Nutrient Journal

      Ginger (also known as Zingiber officinale, family: Zingiberaceae) has been widely consumed as a dietary spice, delicacy, and as a traditional oriental medicine. The rhizome can be used fresh, dried or powdered. Ginger is often applied for treating nausea due to caused by morning sickness during pregnancy, chemotherapy and seasickness.

      Ginger as Testosterone Booster

      Ginger rhizome powder was reported to posses an antioxidant and androgenic activity in doses of 50 mg/kg and 100 mg/kg daily [1]. Ginger administration significantly increased serum testosterone levels at 100 mg/kg [1]. There was also an increases in testosterone at 50 mg/kg daily but it failed to reach statistical significance [1]. A study by Kamtchouing et al. [2] also reported significantly increased serum and testicular testosterone levels as well as increase in weight of the testis and testicular cholesterol level in healthy rats. Another study using doses of 500 mg/kg and 1000 mg/kg indicated that extract of Zingiber officinale possesses pro-fertility properties [3]. Compared with the controls there was a dose and duration dependent increases in the serum testosterone levels and seminal quality [3]. At a very high dose (2000 mg/kg for 35 days), ginger led to slightly reduced weights of testes which might be due to negative feedback reaction from androgenic activity [4].

      Ginger also prevented damage to reproductive organs induced by aluminium chloride [5] as well as cisplatin induced testicular damage [6]. Morakinyo et al. [3], Khaki et al. [7] and Shalaby et al. [8] concluded that ginger may be promising in enhancing healthy sperm parameters.

      Human Study

      One preliminary study by researchers from Tikrit University showed high statistically significant increase of serum hormones (p< 0.01) in infertile men [9]. After 30 week treatment serum testosterone has increased by 17,7%, serum luteinizing hormone by 43,2% and serum follicle-stimulating hormone by 17,6%; dosage of ginger used was not disclosed [9].
      Ginger for Digestive Aid

      Oral ginger was reported to accelerate gastric emptying and stimulate gastric motility (spontaneous movements of the stomach that aid in digestion). Most studies report some beneficial effect on gastric emptying time but mostly during some sort of disease state [10,11]. In healthy individuals ginger also seems to increase gastric emptying via antral contraction stimulation [12]. However, Phillips and colleagues [13] reported that ginger is not associated with an effect on gastric emptying. In animals, ginger and its active constituent [6]-Gingerol were reported to enhance gastrointestinal tract transit [14].

      Other Benefits of Ginger Ingestion

      According to studies by Srivastava [15] and Thomson et al. [21] ginger can be used as natural antithrombotic agent. Ginger has also been recorded as useful remedy in preventing post-operative nausea and vomiting in humans [13] as well as preventing morning sickness during pregnancy [16]. At high doses (500 mg/kg) aqueous extract of ginger exhibits cholesterol-lowering effect [21].

      Joint Health

      Ginger is also often found in joint support supplements. There is little well-designed research, however, ginger was reported to have some effectiveness for relieving joint pain of osteoarthritis and rheumatoid arthritis probably due to its anti-inflammatory [17,18,21] and anti-oxidant activity [17,18].

      Are There Any Side Effects?

      Ginger is considered a safe herbal medicine with only few and insignificant adverse/side effects [1]. Some minor adverse effects such as mild diarrhea have been associated with the use of ginger in humans [19]. Ginger may also cause heartburn and at much higher doses act as a gastric irritant [19]. One study carried out on male diabetic rats concluded that extracts of Zingiber officinale have high safety and intake of Zingiber officinale roots as a drink may be useful for diabetic patients who suffer from sexual impotency [20].

      A 16 day administration of 1000 mg of powdered rhizome of Zingiber officinale appears to have no side effects [13].

        Something tells me that 10g of ginger root powder a day is probably uncomfortable.

        Effect of Eurycoma longifolia extract on androgen biosynthesis

        Norhaniza, A; Ramli, A; Hamid AAH; Johari, MS
        Department of Biochemistry, University of Malaya; Kuala Lumpur, Malaysia

        13th Seminar on Natural Products; Forest Research Institute Malaysia, 5-6 August 1997

        Eurycoma longifolia extract which is believed to have aphrodisiac properties was tested in mice and human testicular

        homogenates. The claimed effect was observed through the ability of the extract to enhance the elevation of the androgen

        level in the homogenates. In vitro analysis using capillary gas chromatography on rat testicular homogenates showed an

        increase in androgen level. The levels of testosterone and its metabolism were seen to be significantly higher with the

        presence of Eurycoma longifolia extract. In vivo studies was carried out by treating male mice through intraperitonial

        injection. The effect of Eurycoma longifolia extract on the serum testosterone level was examined by radioimmunoassay. Our

        observation showed that the serum testosterone level in treated mice was significantly higher than the untreated mice.

        Results obtained suggest that Eurycoma longifolia extract has the ability to increase the biosynthesis of androgen. The

        observed effect could provide the possible explanation of the claimed aphrodisiac properties of the plant.
