Dosage forms and preparation

Dosage Forms: Churna (flower powder), Swarasa (flower juice), Ghrita (flower-processed ghee), Tablet, Capsule

Standard Dosage: 1-3g flower powder twice daily; 5-10ml flower juice with ghee; as component in formulations per classical texts

Bioavailability: Flowers of Calotropis procera/gigantea contain lower cardenolide levels than latex or root bark but still have therapeutic activity. Flavonoids and triterpenoids in flowers have moderate oral bioavailability. The flower is traditionally considered the mildest part of Arka and is used for digestive (Deepana) and respiratory applications. Ghee as anupana enhances lipophilic constituent absorption.

Optimal Timing: Before meals with ghee for digestive stimulation; morning for respiratory conditions

Standardized Extract: Flower extract with documented cardenolide content (lower threshold than root/latex preparations). Total flavonoid content minimum 2%.

Shelf Life: 18 months (flower powder); 2 years (Ghrita); 2 years (capsules/tablets)

Storage: Airtight containers, cool and dry place. Ghrita in glass containers at room temperature or refrigerated for longer storage.

Marker Compounds: Calotropin (at lower levels than other plant parts), Quercetin, Isorhamnetin, Kaempferol, Alpha-amyrin acetate, Uvaol

Extraction Methods

  • Fresh juice expression from flowers
  • Ghee processing (Ghrita Paka with flower juice)
  • Hydroalcoholic extraction (60:40)
  • Aqueous decoction

Synergistic Combinations

  • With ghee for Deepana (digestive fire stimulation)
  • With Sunthi for cough and respiratory support

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.

Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
