Contraindications

• GI Disturbances: High doses (over 5g/day) might cause diarrhea or abdominal discomfort in sensitive people.
• Oxalate Content: It contains low levels of oxalic acid. Therefore, it should be avoided by individuals with recurrent kidney stones unless under medical supervision.
• Bleeding Disorders & Anticoagulants: Due to the presence of ß-sitosterol and flavonoids, caution is advised for those on warfarin or aspirin therapy as it may interact with anticoagulants.
• Pregnancy & Breastfeeding: It is traditionally avoided in early pregnancy due to a lack of sufficient evidence and concerns about potential uterine stimulation.
• Surgery: It's important to tell your doctor if you take any herbal medicines before undergoing surgery because some herbal medicines may interfere with blood clotting and blood pressure, which may increase the risk of bleeding during or after surgery.
• Possible Interactions: It may interact with certain NSAIDs and may affect blood sugar levels if taken with diabetes medications. Careful monitoring of blood sugar levels is critical.
• Liver Toxicity: There is a possibility of liver toxicity associated with oral intake of Amalbedha with liver toxic drugs.
• Alcohol Consumption: Amalbedha users are advised to limit alcohol consumption since it might interact with the body.
• Allergic Reactions: Allergic reactions are rare but possible. If you notice a rash or itching, discontinue use immediately.

Side effects

• Digestive Upset: Rare mild nausea or abdominal discomfort if taken on an empty stomach or in excessive doses.
• Potential Allergies: Individuals with legume allergies should proceed cautiously. Cross-reactivity is not well studied.
