Costus Igneus, also known as the insulin plant, is a species of herb that has been used in Ayurvedic medicine for centuries as a remedy for diabetes. More recently, modern medical research has begun investigating the potential of Costus Igneus as an alternative treatment for managing blood sugar in people with diabetes. However, like all medicinal herbs and plants, Costus Igneus can have side effects, especially when taken in large doses. This article will explore the known side effects and safety concerns around using Costus Igneus as a diabetes therapy.

How Costus Igneus Works
The primary active compounds in Costus Igneus are diosgenin, a steroidal sapogenin, and dioscin, a natural steroid saponin. These chemicals are thought to mimic or stimulate the effects of insulin in the body, hence the nickname “insulin plant.” Insulin is the hormone essential for allowing glucose (sugar) in the bloodstream to enter cells to be used for energy. In type 1 and advanced type 2 diabetes, the body doesn’t produce enough insulin or cells become resistant to insulin. This causes blood glucose levels to remain dangerously high, leading to complications like nerve damage, blindness, kidney failure, and cardiovascular disease. By naturally regulating blood glucose, compounds in Costus Igneus may make it easier for the body to manage diabetes symptoms.
Animal and lab studies indicate Costus Igneus extracts boost the uptake of glucose into muscle and fat cells by activating insulin receptors in cell membranes. The herb also appears to regenerate and protect insulin-producing beta cells in the pancreas. Furthermore, research shows Costus Igneus can inhibit enzymes that breakdown complex carbohydrates into simple sugars during digestion, reducing glucose absorption from food.
However, most studies have been limited to animal models and test tube experiments so far. Robust, large-scale human trials are still needed to verify the efficacy and safety of using Costus Igneus supplements to treat diabetes in people.
Potential Side Effects and Safety Concerns
Given the lack of sufficient human research, the side effects and long-term safety of Costus Igneus supplementation are not fully understood. However, some potential side effects and concerns have been identified:
- Hypoglycemia – Costus Igneus may lower blood glucose too much, increasing the risk of low blood sugar levels, or hypoglycemia. This is especially dangerous for people taking anti-diabetes medications already.
- Digestive issues – High doses of Costus Igneus may irritate the gastrointestinal tract causing diarrhea, nausea, cramping, and bloating.
- Pregnancy risks – Costus Igneus may stimulate uterine contractions so should be avoided during pregnancy. It may also endanger the fetus, with one study finding birth defects in baby rats whose mothers ingested Costus Igneus.
- Surgery complications – Costus Igneus may interfere with blood sugar control during and after surgery, particularly in those on diabetes meds. Stopping Costus Igneus 2 weeks before a scheduled surgery is recommended.
- Toxicity – High doses of Costus Igneus may potentially cause organ damage and other toxic effects. Side effects observed include liver injury, abnormal blood cell counts, jaundice, and kidney toxicity.
- Drug interactions – Costus Igneus may amplify the effects of anti-diabetes medications and increase the risk of hypoglycemia. Blood sugar monitoring is advisable. It may also interact negatively with drugs broken down by the liver.
- Allergic reactions – Some individuals may experience allergic reactions to Costus Igneus, especially with extended use. Reported allergic reactions include rashes, hives, facial swelling, and anaphylaxis. Discontinue use if any hypersensitivity reactions occur.
- Lack of quality control – Herbal supplements like Costus Igneus extract are not strictly regulated. Product quality and active ingredients can vary widely between brands and batches. Only purchase products from reputable companies with independent testing.
Due to the limited evidence and potential side effect risks, medical experts recommend using caution with Costus Igneus for diabetes. Always consult a physician before taking Costus Igneus supplements for proper dosing and monitoring. Certain populations like pregnant or breastfeeding women, children, those with liver/kidney conditions, and surgical patients should avoid use completely until more research confirms its safety.
Recommended Dosage and Potential Benefits
Typical doses of Costus Igneus root powder range from 1-3 grams per day. For diabetes, doses up to 3 grams taken in divided amounts before meals may help reduce post-meal blood sugar spikes. Commercial supplements often provide 250-500 mg Costus Igneus extract per capsule standardized to 4-8% diosgenin content.
When taken under physician guidance and supervision, Costus Igneus may provide the following benefits for diabetes patients:
- Lower fasting blood glucose up to 20-30%
- Reduce HbA1c levels up to 1.5%
- Improve glucose tolerance and insulin sensitivity
- Increase insulin levels and regeneration of pancreatic beta cells
- Delay absorption of dietary carbohydrates
- Provide antioxidant and anti-inflammatory effects
However, blood glucose should be closely monitored for hypoglycemia. Costus Igneus may also allow reducing insulin or oral diabetes medication dosages in some cases. But changing medication regimens should only be done under a doctor’s direction.
In summary, Costus Igneus shows promising potential as a natural adjunct treatment for diabetes management. But the herb requires further study to conclusively demonstrate both its efficacy and long-term safety in human subjects. Patients and doctors should weigh the risks and potential benefits carefully before using Costus Igneus supplements. Proper dosage, monitoring, and precautions are essential to reducing side effects when using this alternative diabetes therapy.
