Question 1

How does Millettia pinnata work for skin diseases?

Accepted Answer

Millettia pinnata contains active compounds including karanjin and pongamol, which demonstrate anti-inflammatory and antimicrobial properties. These flavonoids work by inhibiting pro-inflammatory mediators and disrupting microbial cell membranes. The seed oil also contains fatty acids that support skin barrier function and wound healing. Laboratory studies have shown antifungal activity against various dermatophytes, supporting its traditional use for fungal skin infections. Evidence level: C (preclinical and traditional use data).

Question 2

Does Millettia pinnata interact with any medications?

Accepted Answer

There is limited clinical research on specific drug interactions for Millettia pinnata. Due to the lack of human pharmacokinetic studies, individuals taking prescription medications should consult a healthcare provider before using this herb. The internal use of seed oil is contraindicated due to toxicity concerns, which could potentially compound the effects of other hepatotoxic substances. Topical application appears to have minimal systemic absorption, reducing interaction risk. Evidence level: C.

Question 3

What is the recommended dosage for Millettia pinnata?

Accepted Answer

Traditional Ayurvedic practice uses Millettia pinnata bark as a decoction at 3-6 grams daily. The seed oil (karanja oil) is applied topically to affected skin areas, typically once or twice daily. There is no standardized clinical dosage established through human trials. Internal use of the seed oil is not recommended due to toxicity. Users should follow product-specific instructions or consult a qualified herbalist for individualized dosing. Evidence level: C (traditional use).

Question 4

Is Millettia pinnata safe during pregnancy?

Accepted Answer

Millettia pinnata is considered unsafe during pregnancy and should be avoided. The seed oil contains compounds that may be toxic when absorbed systemically, and insufficient safety data exists for use during gestation. Traditional contraindications explicitly advise against use in pregnant women. Breastfeeding women should also avoid this herb due to lack of safety data. Women who are pregnant or planning pregnancy should consult a healthcare provider before using any herbal preparations containing this plant. Evidence level: C.

Question 5

Can Millettia pinnata seed oil be taken internally?

Accepted Answer

No, Millettia pinnata seed oil should not be taken internally. The oil contains toxic compounds that can cause adverse effects when ingested, including gastrointestinal distress. Traditional and modern herbal practice restricts its use to topical application only for skin conditions, wound healing, and localized anti-inflammatory effects. The bark decoction may be used internally at recommended doses under professional guidance, but the seed oil is strictly for external use. Evidence level: C.

Question 6

What is Millettia pinnata used for in Ayurvedic medicine?

Accepted Answer

In Ayurvedic medicine, Millettia pinnata (karanja) has been traditionally used for treating skin diseases including eczema, psoriasis, and fungal infections. It is also employed for rheumatic conditions, wound healing, and as an anti-inflammatory agent. The seed oil is applied externally, while bark preparations may be used internally at appropriate doses. Traditional practitioners value it for its antifungal, antibacterial, and wound-healing properties. Evidence level: C (traditional use with preclinical support).
