Another plant for sexual "weakness" [erectile dysfunction], available in all health food shops [ just sent one about Tribulus]: Arctium lappa


I don't know why in the 2 articles I sent to you the researchers were using "albino" rats.......

This herb is best prepared as a decoction:that means:  bring some 20 gram of the dried herb with some 3 /4 liter

of water to a boil.Then simmer for another 20-30 minutes  until the liquid is reduced by about one third [500ml]
Strain and drink this amount during the day

Arctium lappa is often used for all kind of skin problems and for urinary stones [a "cleaner"] and the use as a sexual enhancer was not known to me.

Effect of aqueous extract of Arctium lappa L. (burdock) roots on the sexual behavior of male rats.



Arctium lappa L. root has traditionally been recommended as an aphrodisiac agent. It is used to treat impotence and sterility in China, and Native Americans included the root in herbal preparations for women in labor.However, its use has not been scientifically validated. The present study therefore investigated the effects of aqueous extract of Arctium lappa L. roots on sexual behavior in normal male rats.


Seventy-five albino male rats were randomly divided into five groups of 15 rats each. Rats in group 1 (control) were administered 10 mL/kg body weight distilled water (vehicle), group 2 received 60 mg/kg body weight sildenafil citrate (Viagra), while those in groups 3, 4, and 5 were given 300, 600, and 1,200 mg/kg body weight, respectively, of aqueous extract of Arctium lappa L. roots in the same volume. Female albino rats were made receptive by hormonal treatment. Sexual behavior parameters in male rats were monitored on days 3, 7 and 15 by pairing with receptive females (1:3). Male serum testosterone concentrations and potency were also determined.


Oral administration of Arctium lappa L. roots extract at 600 and 1,200 mg/kg body weight significantly increased the frequencies of mount, intromission, and ejaculation frequency (p < 0.05). The latencies of mount and intromission were significantly reduced and ejaculation latency was prolonged. Administration of the extract also reduced the post-ejaculatory interval. The standard drug (Viagra) was more effective than the extract. The extract significantly increased the frequencies of all components of penile reflexes as well as serum testosterone levels, compared with the distilled water controls.The results of this study demonstrate that aqueous extract of Arctium lappa L. roots [ MY REMARK: THIS MEANS SIMPLY MAKING A TEA] enhances sexual behavior in male rats. The aphrodisiac effects of the plant extract may be related to the presence of flavonoids, saponins, lignans and alkaloids, acting via a multitude of central and peripheral mechanisms. These results thus support the traditional use of Arctium lappa L. root extract for treating impotence and sterility.
