Safflower (Carthamus tinctorius) has a long history of use in traditional medicine, particularly in Chinese and Ayurvedic practices. In Traditional Chinese Medicine (TCM), safflower is used to "invigorate blood" and dispel blood stasis, which is believed to help with conditions involving poor circulation, such as varicose veins. The plant's flowers are often included in herbal formulas aimed at improving vascular health and reducing swelling or pain associated with venous insufficiency.

However, while traditional texts support its use for circulatory problems, there is limited modern clinical research specifically investigating safflower’s effectiveness for varicose veins. Some laboratory and animal studies suggest that safflower extracts may have vasodilatory and anti-inflammatory effects, and could improve blood flow. Despite these properties, high-quality human trials addressing varicose veins directly are lacking.

Therefore, the use of safflower for varicose veins is primarily justified by tradition rather than robust scientific evidence. Most recommendations for its use in this context are based on historical usage and theoretical mechanisms rather than proven clinical efficacy.
