Back in 2011 I blogged about her summer herb blend, and it's not too different really, just a difference in proportion due to her age and current particulars.
Astragalus: for strengthening Qi, providing energy while preventing Summer Heat, and in Western terms strengthening the immune system.
Reishi: Adaptogenic, immune balancing, good for the kidneys and lungs.
Billbery: Antioxidant, good for the eyes in particular (and Vida has a recent condition in one of her eyes I'm hoping to at least stop progress on). This fruit is similar to blueberries so they have the benefits of all deep purple fruits.
