The COA of Cassia Seed Extract Powder
Regulatory Status of Cassia Seed Extract
Japan and South Korea
In Japan, low-concentration cassia seed extract can be directly circulated as raw material for herbal teas and general food products. Standardized extracts with high anthraquinone content are classified as Kampo OTC pharmaceuticals and included in the Japanese Pharmacopoeia, which may only be formulated for products indicated for short-term laxative use and alleviation of eye strain. The extract may be added to dietary supplements, though claims of disease treatment are prohibited.
In South Korea, low-concentration roasted cassia seed extract can be freely circulated as a general food raw material. High-purity standardized extracts intended for functional health foods must be listed in the official raw material catalog and complete safety filing procedures.
The United States
The United States complies with relevant FDA regulations governing dietary supplements. Cassia seed extract is classified as a traditional herbal raw material and can be utilized as an ingredient in dietary supplements without undergoing the new dietary ingredient (NDI) notification process. Products may carry wellness statements such as soothing eye discomfort and gently supporting intestinal health. High-potency extracts formulated specifically for laxative purposes require registration as OTC drugs, with restricted daily dosages and usage durations mandated. The FDA does not impose separate bans on the use of cassia seed extract in cosmetics; however, raw materials with high anthraquinone levels must complete safety toxicological assessments, and formulations with strong irritant effects intended for eye contact are prohibited.
EU
Under EU regulations, standardized high-anthraquinone cassia seed extracts may be circulated as medicinal products upon completion of traditional herbal registration under the THMPD directive, with their application limited solely to short-term constipation relief. Low-concentration extracts for topical cosmetic use must be accompanied by a full Cosmetic Product Safety Report (CPSR) prior to market launch.

What Are the Benefits of Cassia Seed Extract?
Cassia Obtusifolia Seed Extract for Constipation
The core active ingredients of cassia seed extract are anthraquinone derivatives such as chrysophanol and emodin. On one hand, these substances stimulate epithelial cells of the large intestinal mucosa to accelerate intestinal peristalsis, shorten the residence time of stool in the intestines and reduce excessive water absorption. On the other hand, they inhibit the reabsorption of water and electrolytes by the intestines, raise the water content inside the intestinal cavity to soften hard stools, and mildly regulate the contraction rhythm of intestinal smooth muscle, delivering dual effects of boosting peristalsis and lubricating the intestines.
It gently alleviates constipation caused by intestinal heat and insufficient intestinal fluid. Unlike harsh stimulant laxatives, it only acts on the large intestine at proper dosages and rarely overstimulates the small intestine to cause diarrhea or abdominal pain.
Cassia Obtusifolia Seed Extract for Eyes
Anthraquinones in cassia seed extract can enter the ocular microcirculation to eliminate excess free radicals in the eyeball and mitigate retinal oxidative damage induced by prolonged exposure to blue light and ultraviolet rays. Meanwhile, they dilate tiny blood vessels around the eyes, accelerate blood and nutrient delivery to the eyes, and relieve dry eyes, eye soreness, ocular distension and blurred vision caused by excessive eye strain.
Its active ingredients also help suppress ocular inflammatory responses and soothe congested and red conjunctiva. Long-term supplementation nourishes the optic nerve and improves blood supply to the fundus, alleviating eye fatigue fundamentally and supporting the health of the lens and retina. It is suitable for daily eye care of people who stare at electronic screens for long hours and use their eyes frequently.
Cassia Obtusifolia Seed Extract for Skin
Anthraquinones and polyphenolic antioxidant ingredients neutralize excess free radicals in the epidermal and dermal layers of the skin, counteracting oxidative aging triggered by ultraviolet rays and electronic light pollution to reduce skin concerns such as fine lines, dullness and sallow complexion. These active substances regulate the secretion of skin inflammatory factors, soothe irritations including redness, sensitivity and acne breakouts, and restrain excessive sebum secretion to balance skin oil and moisture levels.
Meanwhile, they help dilate subcutaneous capillaries, boost skin circulation and metabolism, speed up the elimination of dead keratin and melanin, fade dull pigment spots, and repair the skin barrier. Long-term use brightens skin tone, tightens skin texture and maintains stable and healthy skin condition.

FAQ
Q: What are the side effects of cassia seeds?
A: Cassia seeds contain natural laxative ingredients. Most people experience no discomfort when consuming them in small amounts for a short period, yet various side effects may occur with excessive intake, long-term continuous consumption, or use by specific groups. The most prevalent issues are gastrointestinal troubles including stomach pain, bloating, diarrhea and nausea, which are more severe for those with sensitive stomachs or frequent loose stools. Persistent severe diarrhea leads to loss of essential minerals such as potassium and sodium, resulting in fatigue, palpitations and muscle cramps. Cassia seeds have a mild hypotensive effect, so people with low blood pressure may suffer dizziness and general weakness after taking them. Pregnant women, breastfeeding mothers and young children are not advised to consume them, as they may compromise pregnancy stability and children's intestinal health. Long-term heavy intake can also disrupt women's regular menstrual cycles. High-dose consumption lasting several months increases metabolic strain on the liver and kidneys, potentially causing abnormal liver function indicators, while prolonged intestinal irritation may alter the state of colonic mucosa. In addition, a tiny number of individuals may develop allergic reactions like itchy skin. Anyone taking antihypertensive, hypoglycemic or cardiac medications must consult medical professionals before drinking cassia seed preparations to prevent adverse interactions between herbal ingredients and western medicines that worsen physical discomfort.
Q: Does cassia seed reduce belly fat?
A: Cassia seeds cannot directly burn or break down deep belly fat and only serve as a supportive herbal ingredient for weight management. Containing anthraquinones and soluble dietary fiber, they speed up intestinal peristalsis and cut the intestines' absorption of oil and sugar, relieving abdominal bloating and puffiness caused by constipation. Animal studies also prove extracts of cassia seeds can regulate liver lipid metabolism and slightly lower the risk of visceral fat buildup. However, drinking cassia seed tea alone will not produce noticeable belly slimming results. To truly reduce belly fat, you need to combine calorie control, balanced meals, regular cardio and core workouts. Besides, continuous long-term consumption of cassia seeds is not recommended, as it may lead to intestinal dependence, diarrhea and other discomforts.
