Caterpillar Fungus
Cordyceps sinensis
For centuries, Tibetan yak herders noticed their animals seeking out a strange dark sprout in the high meadows each spring, and grazing there with unusual vigor. That observation carried the fungus into both Tibetan and Chinese medicine, where it was gathered by hand from alpine slopes and traded down into the lowlands as one of the most valuable tonics known. In traditional Chinese medicine it was classed as a tonic for the lungs and kidneys, used to support breath, stamina, and recovery after long illness or exhaustion, and it was often reserved for emperors, elders, and the depleted. Its scarcity and the difficulty of the harvest, high on wind-scoured slopes, only deepened its reputation as a treasure of the mountains.

Traditional preparations.
The classic and most traditional way cordyceps has been taken, simmered slowly into a nourishing broth alongside chicken, duck, or pork, often with other tonic herbs added.
Traditionally, 3 to 5 whole dried pieces are simmered gently with meat and a few slices of ginger for 1 to 2 hours, then the broth and softened pieces are eaten together.
A simpler, everyday preparation using the powdered form, steeped like a tonic tea.
Traditionally, half a teaspoon of powdered cordyceps is steeped in 250 ml of just-boiled water for 10 minutes, then strained and sipped warm.
Safety.
Cordyceps may cause mild digestive upset and can have blood-thinning and immune-stimulating effects, so use caution with anticoagulants, immunosuppressants, autoimmune conditions, or diabetes medication. It's best avoided during pregnancy and breastfeeding, and wild-sourced product is often counterfeited or adulterated, so buy from a reputable supplier.
