can zi zui tang interfere with your birth control?

Hello keeeezysaidso,

Do you mean zi xui tang bee pollen?

If so, as of October 24, 2012, The Food and Drug Administration (FDA) advised consumers not to purchase or use "Zi Xui Tang Bee Pollen Capsules", also referred to as "Zi Xui Tang Beauty, Face & Figure Capsule", a product promoted and sold for weight loss and body reshaping.
"FDA laboratory analysis confirmed that “Zi Xiu Tang Bee Pollen Capsules” contains sibutramine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. The product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This product may also interact, in life-threatening ways, with other medications a consumer may be taking.

Consumers should stop using this product immediately and throw it away. Consumers who have experienced any negative side effects should consult a health care professional as soon as possible. "
