An Ayurveda herb used traditionally as an aphrodisiac and pro-fertility compound, touted to increase masculinity and enhance youthfulness during aging. It belongs to the category of Vrishya rasayana alongside Anacyclus Pyrethrum.

Sources and Usage
Interactions with Hormones
A defatted ethanolic extract of the seeds of Byronia Laciniosa, at three dosages daily for 28 days in rats (50mg/kg bodyweight, 100mg/kg and 150mg/kg) showed dose dependent increases in serum Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), and Testosterone; the serum level of testosterone reaching approximately 6.5ng/mL after 150mg/kg whereas control and 50mg/kg bodyweight (insignificantly different) hovered around 1ng/mL.
The mechanism is hypothesized to be through hypothalamic stimulation, due to the above three hormones all increasing; however, this has not been directly tested.
The ethanolic extract of the seeds appears to be a potential testosterone enhancer in fertile male rats
Interactions with Sex Organs
Bryonia Laciniosa is able to dose-dependently increase the weight of male sex organs (epididymus, testes, and prostate). Spermatogenesis was increased in this same study, as well as fructose content of semen (nutrition for semen cells). These beneficial changes for fertility were accompanied by an aphrodisiac effect in mice, also dose-dependent.
An increase in sex organ weight of male rats has been noted alongside pro-libido effects, suggesting that testosterone plays a role
Immunology and Inflammation
Byronia Laciniosa is touted as an anti-pyretic (against fever) and was found to exert anti-fever effects (at 500mg/kg) at an efficacy similar to the control drug, paracetamol (150mg/kg).. This study also noted analgesic (painkilling) actions in a dose-dependent manner, although even 500mg/kg Byronia Laciniosa was less effective (52.61% inhibition relative to control) than 100mg/kg Aspirin (68.87% inhibition).
Preliminary evidence suggests that shivlingi seeds may be able to reduce symptoms of the fever with a potency lesser than that of paracetamol
Safety and Toxicity
Tested doses of a methanolic extract of Byronia Laciniosa at 125mg/kg and 250mg/kg over a period of 14 days in rats did not adversely affect measured liver enzymes.
