Frequently Asked Questions about Cao Dou Kou Extract
What is Cao Dou Kou / Katsumada Galangal (Alpinia katsumadai) seed extract?
Cao Dou Kou is the Chinese name for the seed of Alpinia katsumadai, an aromatic plant of the ginger family (Zingiberaceae) known in English as Katsumada galangal or grass cardamom; the dried seed is known in pharmacy as Semen Alpiniae Katsumadai. This alcohol-free version is a vegetable-glycerin glycerite of the dried seed. It began as a culinary spice and is also documented in the Korean pharmacopeia. It is a food-familiar aromatic seed and generally well tolerated; if you are pregnant or nursing, it is best avoided as a precaution because information is limited. Please read the notes below.
What is the difference between the alcohol-free and tincture versions?
Both are liquid extracts of the same Alpinia katsumadai seed; only the solvent differs. This alcohol-free version is a glycerite made with vegetable glycerin and purified water, giving a milder carrier for those who prefer to avoid alcohol. The tincture uses organic alcohol with vegetable glycerin and water, the classic conventional method that yields a concentrated extract with a long shelf life. Choose the glycerite if you prefer no alcohol; choose the tincture for a traditional alcohol-extracted format. The seed inside is identical, and the same notes apply to both.
How is Cao Dou Kou different from the other cardamoms and galangals?
The ginger family has many similar-looking, similarly named spices, so the botanical name matters. Cao Dou Kou is Alpinia katsumadai (grass cardamom). It is different from black cardamon, which is Alpinia oxyphylla (Yi Zhi Ren); from galangal, Alpinia galanga; from lesser galangal, Alpinia officinarum; from cao guo, Amomum tsaoko; from round cardamom / bai dou kou, Amomum kravanh; from true cardamom, Elettaria cardamomum; and from grains of paradise, Aframomum melegueta. All are aromatic ginger-family spices with different traditional uses. We label ours clearly as Alpinia katsumadai so it is not confused with the others.
How do I use Cao Dou Kou / Katsumada Galangal liquid extract?
Shake well first. Use the number of drops and the frequency shown on the label, in a little water, tea or juice, or as directed by your practitioner. This alcohol-free glycerite has a milder carrier. Store in a cool, dry place away from direct light, and shake before each use.
Is Cao Dou Kou right for everyone? Safety information.
Cao Dou Kou is a food-familiar aromatic spice and is generally well tolerated. A few sensible cautions still apply. Pregnancy and nursing: because there is not enough information, it is best to avoid it during pregnancy and breastfeeding, or consult your practitioner first. Digestive: in some people it may cause mild stomach upset; if so, reduce the amount or stop. Medications: if you take any medication or have a medical condition, consult a qualified healthcare practitioner before use. Keep to sensible use. Do not use it to self-treat any medical condition - see a qualified doctor instead. Do not give it to infants or young children. Store as directed on the label. Keep out of reach of children.
