Rose Milk Tea's method, with goji in the pot. Three jujubes, 5.5 grams of goji and 1.2 grams of sliced ginger simmer in 160 millilitres of water for six or seven minutes, until the liquid runs amber. The black tea, 1.2 grams, steeps for one minute; six lightly crushed rose buds follow off the heat for two or three; the milks go in last, after straining. The goji sets it apart: 5.5 grams, against 5 in the Woman Well-Being Brew and none in the plain Rose Milk Tea, and the recipe credits its ruby-orange zeaxanthin pigment with colouring the base. It has the least ginger of the three, and no cardamom or licorice.
The tagline promises a ruby lift and the effects list says immune. For the lift, the Journal's note on caffeine says a good deal of well-controlled work suggests that for a habitual drinker it is mostly restoration, not a gain. The immune claim has less under it. The recipe gives the ginger a gentle immune push, but the ginger note calls immunity claims unsupported: the one well-designed test, 3 grams a day for outpatients with COVID-19, cleared virus in 41.6 per cent on ginger and 42.8 on placebo. No note tests goji's zeaxanthin. The Chinese herbal brews note places goji among the Solanaceae, a tomato relative, so a single-ingredient goji tea from a traceable supplier carries no aristolochic acid risk.
Sweetness is set to taste: 8 millilitres of condensed milk is one to two teaspoons. The caution that matters is goji with warfarin. The Chinese herbal brews note describes a 61-year-old woman stable on warfarin whose INR reached 4.1 after four days of three to four glasses of concentrated goji tea daily; it returned to range within a week of stopping. The note gives no gram amount, so this cup, with 5.5 grams of goji, cannot be set against her case, and the advice stands: anyone on an anticoagulant should treat a daily goji habit as a change in medication.
