Frequently Asked Questions (FAQs)

Q: What is Blue Tea and how do I make it? A: Blue Tea is an herbal infusion made from dried Aprajita (Butterfly Pea) flowers. Steep 5-6 flowers in hot water for 5-10 minutes. The tea is naturally blue, caffeine-free, and turns purple when you add lemon juice.

Q: Can I drink Blue Tea daily? A: Yes, 1-2 cups of Blue Tea daily is safe and beneficial for most adults. It provides antioxidants, supports memory, and promotes relaxation without caffeine.

Q: Is Aprajita the same as Sankhpuspi? A: No, though both are Medhya Rasayana (brain tonics) in Ayurveda. Aprajita (Clitoria ternatea) has blue flowers, while Sankhpuspi (Convolvulus pluricaulis) has white flowers. Both support memory but have different chemical profiles.

Q: Can Aprajita help with hair health? A: Yes, Aprajita is traditionally used as a hair tonic. The anthocyanins improve blood circulation to the scalp, strengthen hair follicles, and may help prevent premature graying. Use as a hair rinse or oil infusion.

Q: Why does the tea change color with lemon? A: Aprajita’s blue color comes from anthocyanins, which are pH-sensitive pigments. In neutral water they appear blue; adding acidic lemon juice shifts the pH, changing the color to purple or pink. This is natural chemistry, not any additive.
