Question 1

How does Pterocarpus indicus work medicinally?

Accepted Answer

Pterocarpus indicus contains active compounds including flavonoids, tannins, pterocarpol, and homopterocarpin that contribute to its medicinal effects. The tannins provide astringent properties useful for wound healing and treating diarrhea by reducing inflammation and tightening tissues. Flavonoids offer antioxidant effects that may support skin health. For diabetes, the plant's constituents may help regulate blood glucose levels, though the exact mechanism requires further study. Evidence Level C indicates these effects are supported by preliminary research and traditional use rather than robust clinical trials.

Question 2

Does Pterocarpus indicus interact with diabetes medications?

Accepted Answer

Pterocarpus indicus may potentially interact with antidiabetic medications. Since the herb has been used traditionally for managing blood sugar, combining it with prescription diabetes drugs like metformin or insulin could theoretically cause additive effects, leading to hypoglycemia (low blood sugar). Patients taking diabetes medications should consult their healthcare provider before using Pterocarpus indicus and should monitor blood glucose levels closely. Evidence Level C means interaction data is limited and based primarily on theoretical concerns and traditional use patterns.

Question 3

What is the recommended dosage for Pterocarpus indicus?

Accepted Answer

For adults, the traditional dosage of Pterocarpus indicus bark decoction is 5-10 grams taken twice daily. For external applications, leaves can be prepared as a poultice applied directly to affected skin areas or wounds. These recommendations are based on traditional use rather than standardized clinical studies (Evidence Level C). Dosage should be individualized based on the specific condition being treated. Always consult a qualified healthcare practitioner or medical herbalist for personalized dosing guidance before starting any herbal regimen.

Question 4

Is Pterocarpus indicus safe to use during pregnancy?

Accepted Answer

Pterocarpus indicus is considered unsafe during pregnancy and is contraindicated for pregnant women. The herb contains compounds that may stimulate uterine contractions or potentially affect fetal development. Traditional use guidelines explicitly advise against use during pregnancy. Women who are breastfeeding should also avoid this herb, as safety data for lactation is lacking. Any pregnant woman considering herbal treatment should consult a qualified healthcare provider. Evidence Level C indicates this safety assessment is based on traditional knowledge and theoretical concerns rather than clinical studies.

Question 5

What conditions does Pterocarpus indicus treat?

Accepted Answer

Pterocarpus indicus is traditionally used to treat skin diseases, diarrhea, wounds, edema, and diabetes. The bark is commonly prepared as a decoction for internal use, while leaves are applied externally as poultices for skin conditions and wound healing. As the national tree of the Philippines, this Southeast Asian species holds significant cultural and medicinal importance throughout the region. Evidence Level C indicates these traditional uses are supported by preliminary phytochemical research and historical use, though well-designed clinical trials are needed to confirm efficacy.

Question 6

What side effects can Pterocarpus indicus cause?

Accepted Answer

The primary reported side effect of Pterocarpus indicus is gastrointestinal upset, which may include nausea, stomach discomfort, or diarrhea. These effects are generally mild and may be reduced by taking the herb with food or adjusting the dosage. Due to limited clinical research (Evidence Level C), the complete side effect profile is not fully documented. Individuals with sensitive digestive systems or pre-existing GI conditions should use caution. Discontinue use if adverse symptoms persist or worsen, and consult a healthcare provider.
