Tangeretin is found in the peels of citus fruits. It appears some small animal studies have found interaction between it and Tamoxifen. However, the dose was much higher than that found in the amount normally consumed in food daily. The studies caution against supplement forms (high doses) while on Tamoxifen. I don't know of any harm in consuming citrus, in fact there are many phytochemicals in citrus, like limonene, that have shown benefit in breast cancer.
