The Short Answer
Carthamus Leaf contains hydroxysafflor yellow A (HSYA) and safflower polysaccharides (SPS) that inhibit platelet aggregation through PI3K/AKT pathway modulation and enhance immune cell cytotoxicity. These compounds demonstrate anti-inflammatory effects by suppressing IL-6, IL-1β, TNF-α, and COX-2 expression in laboratory studies.

Origin & History
Natural habitat
Carthamus Leaf is derived from Carthamus tinctorius, commonly known as safflower, an annual plant native to the dry temperate plains of Central and West Asia, North Africa, and the Middle East. Its leaves are valued in functional nutrition for their circulatory, anti-inflammatory, and detoxifying properties, particularly supporting cardiovascular and liver health.
“In traditional Unani, Tibetan, and Chinese medicine, Carthamus Leaf has been revered for centuries as the "leaf of flowing blood." It was traditionally used to dispel stagnation, ease pain, support menstrual regulation, and cleanse the liver, symbolically linked to vitality and the restoration of inner rhythm.”Traditional Medicine
Scientific Research
Research, including in vitro and animal studies, supports Carthamus Leaf's traditional uses, highlighting its ability to promote blood circulation, reduce inflammation, and support liver detoxification. Studies indicate its potential for cardiovascular and uterine health benefits, primarily attributed to its flavonoid and phenolic acid content, though human clinical trials are ongoing.

Recommended intake is 1–2 grams per day of dried leaf infusion, or .
Nutritional Profile
- Flavonoids: Including quercetin, kaempferol, and luteolin, offering antioxidant and anti-inflammatory benefits.
- Phenolic Acids: Such as chlorogenic acid, contributing to antioxidant and metabolic support.
- Saponins: Bioactive compounds that may support cardiovascular and detoxification pathways.
- Trace Minerals: Including iron and potassium, essential for blood health and electrolyte balance.
How It Works
Mechanism of Action
Hydroxysafflor yellow A (HSYA) inhibits thrombosis by suppressing PI3K/AKT pathway, increasing BAD expression while decreasing Bcl-2, and enhancing GSH/GSSG balance with elevated SOD levels. Safflower polysaccharides (SPS) trigger G0/G1 cell cycle arrest, inhibit mTOR signaling, and enhance NK cell cytotoxicity while stimulating pro-inflammatory cytokines via NF-κB activation in lymphocytes and macrophages. These compounds collectively reduce inflammatory mediators IL-6, IL-1β, TNF-α, and matrix metalloproteinases MMP-2/9.
Clinical Evidence
Current evidence derives primarily from in vitro and animal studies, with no published human clinical trials providing quantified patient outcomes. Laboratory studies demonstrate SPS induced significant apoptosis in HN-6 cells (p<0.05) and inhibited tumor xenografts with measurable changes in Bcl-2/COX-2 reduction and increased Bax/cleaved caspase-3 expression. Animal studies show SPS reversed NK cell inhibition in T739 lung cancer mice and enhanced cytotoxic T lymphocyte activity. While traditional use spans cardiovascular disease and diabetes treatment from 1978-2025 without reported adverse events, controlled human trials with statistical endpoints are lacking.
Safety & Interactions
No specific safety data, drug interactions, or contraindications are documented in available research literature. HSYA's platelet aggregation inhibition may theoretically interact with anticoagulant medications like warfarin or heparin, though this remains unconfirmed by clinical studies. Traditional clinical use for cardiovascular diseases and diabetes over several decades suggests general tolerability, but formal safety profiling is absent. Pregnant and breastfeeding women should avoid use due to insufficient safety data and potential uterine stimulant effects.

Frequently Asked Questions
What are the main active compounds in Carthamus Leaf?
The primary bioactive compounds include hydroxysafflor yellow A (HSYA), hydroxysafflor yellow B (HSYB), and safflower polysaccharides (SPS) including purified fractions HH1-1, SF1, and SF2. These compounds are responsible for the anti-inflammatory, antioxidant, and cardiovascular effects observed in laboratory studies.
How does Carthamus Leaf affect blood circulation?
HSYA inhibits platelet aggregation and thrombosis through PI3K/AKT pathway modulation, while enhancing antioxidant balance via increased GSH/GSSG ratios and SOD levels. These mechanisms support improved vascular function and blood flow in preclinical models.
Is there clinical evidence for Carthamus Leaf benefits?
Current evidence is limited to laboratory and animal studies, with no published human clinical trials providing quantified patient outcomes. While traditional use spans decades without reported adverse events, controlled human studies with statistical endpoints are needed to confirm therapeutic efficacy.
Can Carthamus Leaf interact with blood thinning medications?
HSYA's demonstrated platelet aggregation inhibition suggests potential interactions with anticoagulant drugs like warfarin or heparin, though this remains theoretical. No formal drug interaction studies have been conducted to confirm or quantify these potential effects.
What is the difference between Carthamus Leaf and safflower oil?
Carthamus Leaf contains flavonoids, polysaccharides, and hydroxysafflor compounds with anti-inflammatory and cardiovascular activities, while safflower oil is extracted from seeds and primarily contains oleic and linoleic fatty acids. The leaf and oil have distinctly different bioactive profiles and traditional applications.
Is Carthamus Leaf safe to use during pregnancy and breastfeeding?
Carthamus Leaf has traditionally been used to support menstrual and uterine health, but it is not recommended during pregnancy as it may stimulate uterine contractions. Women who are breastfeeding should consult a healthcare provider before use, as safety data in this population is limited. It is best to avoid this ingredient during pregnancy and seek professional medical guidance if considering use while breastfeeding.
What is the recommended daily dosage of Carthamus Leaf and when should I take it?
Typical supplemental dosages of Carthamus Leaf range from 500–2,000 mg daily, though optimal amounts vary based on individual health goals and product concentration. For blood circulation and general wellness support, taking it with meals may improve absorption and reduce potential digestive sensitivity. Always follow the dosage instructions on your product label or consult a healthcare practitioner to determine the appropriate amount for your specific needs.
Who should avoid taking Carthamus Leaf supplements?
Carthamus Leaf should be avoided by pregnant women, those with a history of miscarriage, and individuals taking anticoagulant or antiplatelet medications without medical supervision. People with allergies to plants in the Asteraceae family (such as ragweed or chrysanthemums) may experience cross-reactivity and should exercise caution. Additionally, those with hormone-sensitive conditions should consult their healthcare provider before use due to its effects on menstrual and hormonal regulation.
