The Origins and Traditional Use of Cassia Tea
Cassia tea is made from the seeds of the Cassia tora plant, a wild herb also known as Jue Ming Zi in Traditional Chinese Medicine (TCM). In both TCM and Ayurveda, these seeds have been a staple remedy for centuries. Traditional practitioners often prescribe cassia seeds to 'clear liver heat', which is believed to be the root cause of many ailments, including specific eye and digestive issues. The cooling nature of the tea is thought to soothe inflammation and restore balance within the body.
Key Health Benefits of Cassia Tea
Cassia seed tea offers a range of potential health benefits, supported by both traditional use and some modern scientific inquiry.
Vision and Eye Health
For many, the most significant benefit of cassia tea is its positive effect on vision and eye health. Traditionally used to treat redness, irritation, and blurry vision, recent studies have supported these claims. Research has found that cassia tea can improve symptoms of dry eye, reduce intraocular pressure, and enhance near vision, particularly in those with presbyopia. Its potent antioxidant properties help combat the oxidative stress that can damage eye tissue.
Digestive Wellness and Laxative Effects
Cassia tea is well-regarded for its ability to promote digestive health. The seeds contain anthraquinone derivatives, which give the tea mild laxative properties. This makes it an effective remedy for constipation by moistening the intestines and promoting bowel movement. For those with bloating, indigestion, or flatulence, a cup of cassia tea can offer soothing relief.
Liver and Detoxification Support
As a cornerstone of liver support in TCM, cassia seed tea helps in the body's natural detoxification processes. By clearing 'liver heat' and improving the flow of 'Qi', it assists in removing toxins and waste. This detoxifying action is often linked to the tea's benefits for skin health and overall clarity.
Blood Pressure and Cholesterol Regulation
Certain components in cassia seeds have been shown to help control high blood pressure and regulate cholesterol levels. Its cooling properties can help alleviate symptoms like dizziness and headaches that are associated with elevated blood pressure due to liver Yang hyperactivity.
Antioxidant and Anti-inflammatory Properties
Cassia seeds are a rich source of antioxidants and anti-inflammatory compounds. Studies have shown that the antioxidant activity of cassia seed extract surpasses that of other common health supplements like Vitamin C and wolfberry. This powerful free-radical scavenging effect helps protect the body's cells from damage and reduces inflammation, contributing to overall health and wellness.
How to Prepare Cassia Seed Tea
Preparing a simple cassia seed tea is straightforward and can be customized to your taste. Here is a basic recipe:
- Roast the seeds: Take 1-2 teaspoons of clean cassia seeds and lightly roast them in a pan over low heat for 5-10 minutes until fragrant. You can also use a microwave or oven.
- Crush and Steep: Crush the cooled, roasted seeds lightly to help release their flavor and compounds. Place them in a cup.
- Add Water: Pour 250ml of boiling water over the seeds.
- Infuse: Let the seeds steep for 5-10 minutes. The tea can be re-brewed several times.
- Optional Additions: For enhanced flavor or benefits, consider adding honey, chrysanthemum, or goji berries.
Potential Side Effects and Considerations
While generally safe, cassia tea should be consumed with awareness of its potential effects. Its laxative action means that excessive or long-term use can lead to stomach cramps, diarrhea, and electrolyte imbalances. It is not recommended for pregnant women or individuals with diarrhea, as its purging nature can be risky. Always use cassia seed tea for short periods and consult a healthcare provider for any pre-existing conditions.
Comparison Table: Cassia Seed Tea vs. Cassia Cinnamon
It is crucial not to confuse the herbal cassia seed tea (Cassia tora) with cassia cinnamon (Cinnamomum aromaticum), a common spice, as they have different properties and safety profiles.

|---|---|---|
| Source | Seeds of the Cassia tora plant | Bark of the cassia tree |
| Primary Uses | Eye health, digestive aid, liver support | Flavoring, blood sugar control, antioxidant |
| Active Compound | Anthraquinone derivatives (sennosides) | Cinnamaldehyde and high levels of coumarin |
| Laxative Effect | Mild to moderate, supports bowel movement | Minimal to none |
| Flavor Profile | Mild, nutty, and slightly sweet | Strong, spicy, and bitter |
| Key Caution | Not for long-term use due to laxative effects | High coumarin content can cause liver damage with high or prolonged use |
Conclusion: Making Informed Choices About Cassia Tea
Cassia tea offers several traditional health benefits, especially for those seeking to improve eye health, aid digestion, or support liver function. Its antioxidant and anti-inflammatory properties add to its wellness appeal. However, it is a potent herbal remedy, not a simple beverage, and its laxative effects require cautious, short-term use. By understanding its specific benefits and potential side effects, and differentiating it from the more common cassia cinnamon, you can make an informed decision about whether to incorporate this herbal infusion into your health routine.
