Thank you for posting that. I did a quick WEB search. I was not aware that ginseng could be the cause of headaches, or increased coagulation factors. (see links)
Of more interest for this forum are the possible oestrogenic effects.
Good or bad is beyond me. There is a suggestion that it stimulates receptors and another that it blocks blood vessel growth, and a third that it has oestrogenic effect.
Maybe somebody has some thoughts.

"People who take Ginseng and have estrogen-dependent malignancies (breast cancer) may need to avoid taking Ginseng, as it could increase growth rates of cancerous cells. There are two significant drug interactions with Ginseng. Ginseng can affect platelet adhesiveness and blood coagulation."

"Treatment with 17beta-estradiol or ginsenoside-Rb1 increased expression of the progesterone receptor, pS2, and estrogen receptor in MCF-7 cells and of AP-1-driven luciferase genes in COS cells. Although these data suggest that it is functionally very similar to 17beta-estradiol, ginsenoside-Rb1 failed to displace specific binding of [(3)H]17beta-estradiol from estrogen receptors in MCF-7 whole-cell ligand binding assays. Our results indicate that the estrogen-like activity of ginsenoside-Rb1 is independent of direct estrogen receptor association."

"Ginseng extracts contain a variety of active ingredients and have been shown to promote or inhibit angiogenesis, depending on the presence of different ginsenosides that exert opposing effects on blood vessel growth. Leung et al. in this issue of the British Journal of Pharmacology report that Rb1, a ginsenoside that constitutes only 0.37–0.5% of ginseng extracts (depending on manufacturing and processing methods), blocks tube-like network formation by endothelial cells in vitro. At the molecular level, Rb1 binds to the oestrogen receptors and stimulates the transcription of pigment epithelium-derived factor that, in turn, inhibits matrix-driven capillary morphogenesis."
