Annona muricata. The bottle uses the leaf. Caribbean tables know the fruit as soursop, graviola, guanábana.
Why “ancient” is the right word
Soursop leaf has been a night tea across the Caribbean for generations. Antigua’s own plant list, in the FAO country report on plant genetic resources, records soursop tea as a soporific — taken to invite sleep — and the bush as something boiled to bring on a sweat and ease a fever. Coconut oil is the island fat. Saffron is the old dye and kitchen gold of the Mediterranean and Persia, Super Negin the deep-red grade. Chlorophyll is the green of the leaf made visible.
None of that is a new molecule with a patent number. The SwissX method is specific: three days on a bain-marie, the extract carried in cold-pressed virgin coconut oil, Super Negin infused only after the oil cools, then strain and tint. The glass shows pure oil. No visible threads. That method is the house lock. The ingredients are the ancient part.
Cellular restoration — what the bottle is saying
The feature line is proprietary cellular restoration in superfoods. Skin and hair take the oil on the surface, where a fat can sit, soften, and carry the leaf and the saffron. By mouth it is a teaspoon a day, food grade, in the same family as a finishing oil. The claim is restoration as a superfood practice: feed the cell with leaf, green, and gold fat. It is not a licence to say the bottle treats, cures, or prevents a disease. That line is closed on purpose.
The four materials
100% pure soursop leaf extract. Not seed oil. Seed oil is a different material, richer in annonacin, and it is not what goes in this bottle.
Cold-pressed. The carrier. The mouthfeel. The thing that lets the leaf leave the pot and live in a dropper.
About 0.05 g in every 30 ml, infused after the oil cools so the threads give colour and aroma without cooking off.
The tint. Strain and tint only — the finished bottle is oil, not a suspension of plant bits.
Grown on SoilBooster, recorded seed to sale
The plants in the house oil, and the plants on the Shirley’s flavor card, are grown with SwissX SoilBooster — invasive sargassum seaweed, carbonized with coconut, neem and farm manure into the soil amendment. The same landing is cut for fucoidan and iodine. Every product from this ground — the comfort oil, the 250 ml, the packaged lines, and SoilBooster — is tested at SwissX Labs Zurich and at the Department of Analytical Services, Antigua and Barbuda. Same two labs. Same lot line.
The carbon footprint is measured against the full blockchain recording from seed to sale: planting, SoilBooster application, harvest, the three-day bain-marie, bottling, and the shop handoff. The chain is the ledger of that path. It is not a dollar carbon-credit figure on this label. No credit price sits on the comfort oil.
How to take it
- One teaspoon daily by mouth.
- The same oil on damaged hair and on skin.
- Not for inhalation. Not a vape. Not a nebuliser oil.
- Chef first, anointing second. If olive oil is on the plate, it is Kasandrinos from Laconia — single source, never blended into this bottle.
A quiet safety note
Caribbean kitchens have used the leaf as tea for sleep and fever-sweat. Separate from that tradition, French Caribbean research has associated heavy, long-running consumption of soursop fruit and leaf preparations with atypical parkinsonism, and has pointed at annonacin. This bottle is a food-grade comfort oil in teaspoon amounts, not a high-dose leaf drug. It is not advised in pregnancy, for children, or as a replacement for medical care. If you are under a doctor for a neurological condition, ask them before a daily leaf oil.
