Padang cassia is a type of cinnamon. It is prepared from the bark of a small tree found in Southeast Asia. Padang cassia is less expensive than other cinnamons such as cassia cinnamon and Ceylon cinnamon and is the most common type sold in the US.
People use Padang cassia for prediabetes, diabetes, obesity, and many other conditions, but there is no good scientific evidence to support these uses.
In food and beverages, Padang cassia is used as a flavoring agent.
Is It Effective?
NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
- A grouping of symptoms that increase the risk of diabetes, heart disease, and stroke (metabolic syndrome). Early research shows that taking Padang cassia can lower systolic blood pressure (the top number), blood sugar, and body fat in people with metabolic syndrome. It does not seem to lower diastolic blood pressure (the bottom number) or cholesterol.
- Obesity. Early research shows that taking Padang cassia can help to reduce body fat in people who are overweight or obese.
- A hormonal disorder that causes enlarged ovaries with cysts (polycystic ovary syndrome or PCOS). Early research shows that taking Padang cassia can help regulate the menstrual cycle in women with polycystic ovary syndrome (PCOS).
- Diabetes.
- Prediabetes.
More evidence is needed to rate the effectiveness of Padang cassia for these uses.
Is it Safe?
Padang cassia contains chemicals that seem to improve how the body handles blood sugar and how it responds to insulin. These effects may improve blood sugar control in people with diabetes.
When taken by mouth: Padang cassia is LIKELY SAFE when taken in amounts typically found in food. It is POSSIBLY SAFE when taken as a medicine in doses up to 1500 mg daily for up to 6 months. However, when it is taken in doses greater than 1500 mg daily for a long period of time, it is POSSIBLY UNSAFE. Padang cassia contains a chemical called coumarin. In people who are sensitive, coumarin might harm the liver.
