Aphrodisiac. An aphrodisiac is a substance alleged to increase libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior. [1] [2] [3] These substances range from a variety of plants, spices, and foods to synthetic chemicals.
It’s said to relax blood vessels and increase blood flow, but research is limited and mixed. For example, one older study looked at roughly 60 men and women with SSRI-induced dysfunction.
Bilobalide is important for producing several of the effects of Ginkgo biloba extracts, and it has neuroprotective effects, [3] [4] as well as inducing the liver enzymes CYP3A1 and CYP1A2, [5] which may be partially responsible for interactions between ginkgo and other herbal medicines or pharmaceutical drugs.
Ginkgolide B, specifically, is a diterpenoid trilactone with six five-membered rings. It contains a spiro[4,4]-nonane carbocyclic ring, a tetrahydrofuran ring, and a very specific tert-butyl group at one of the rings (Figure 1).
Prediabetes, often considered the step before diabetes, is when you have higher than usual blood glucose (blood sugar) levels. Your levels aren’t high enough to be classified as type 2 diabetes.
Analyses of the powder of Ginkgo biloba capsules revealed the presence of ginkgotoxin. However, as most oral supplements are made from the leaves, which contain only small amounts of ginkgotoxin, [9] below the level of toxicological relevance. [10] Ginkgotoxin-5'-glucoside is a derivative of ginkgotoxin that possesses a glycosyl in the 5' position.
A study by Wolbold et al. (2003) found that the median CYP3A4 levels measured from surgically removed liver samples of a random sample of women exceeded CYP3A4 levels in the livers of men by 129%. CYP3A4 mRNA transcripts were found in similar proportions, suggesting a pre-translational mechanism for the up-regulation of CYP3A4 in women.
