Long, long ago during the Satya Yuga, or Golden Age, of Vedic legend, humans spent most of their time absorbed in deep meditation, subsisting on the prana (vital energy) of sunlight and the breath. One day, according to legend, a piece of black tar fell from the sky and a curious onlooker tasted it and suffered indigestion. Lord Brahma administered hot water as a cure, and all was well.
This story illustrates two important principles of Ayurveda: First, good digestion and elimination—both mental and physical—are crucial to health. Second, hot water helps carry beneficial substances into the body and encourages waste products and toxins to leave. In other words, when you drink tea, you get the prana flowing.
But there's more to it than just drinking tea. What and when you drink, the quality and flavor of the herbs, and the tea's virya (energy) are also important. For instance, ginger's sweet, spicy flavor stokes the agni (digestive fire) and is ultimately nourishing, whereas the spicy, warming flavors of cayenne pepper—although invaluable for treating colds and flu—are too stimulating for cayenne to be used alone as a tea.
You can drink most teas during any time of year, but some are more effective during winter. Licorice tea, for instance, has a bittersweet flavor and cooling energy that can help soothe a dry or sore throat and aid digestion. Hot lemon and mint also help digestion as well as clarify the mind, senses, and emotions.
But the best tea for winter days, especially if you aren't feeling well, is holy basil, or tulsi. The name means "incomparable one," and the herb comes from one of India's most sacred plants, according to Prashanti de Jager, founder of Om Organics, an Ayurvedic herb and tea producer. "This nutritive, warming tea is a first-reach herb for any cough, cold, or flu," de Jager explains. "Besides reducing fever, it promotes healthy digestion and detoxification at the physical and mental levels."
"Whether a substance or action is a food, a medicine, or a poison to the body/mind depends on the circumstances in which it is taken," says Dr. Robert Svoboda, a renowned Ayurvedic physician and teacher. Use this guide to drink the right tea at the right time.
