Deep Dive
The Marking Nut Tree contains alkaloids, primarily strychnine and brucine. While strychnine is famous for its toxicity in raw form, in controlled, purified doses, it acts as a powerful stimulant for the central nervous system and respiration. Traditional practitioners use processed seeds to treat indigestion (specifically with acid reflux) and stubborn coughs where the phlegm is hard to expel. It is also applied topically to treat sores and swelling. The key here is processing—the seeds must be steamed or fried with vinegar to reduce toxicity before use.
Natural Food Sources
While the Marking Nut Tree itself is a medicinal plant rather than a common kitchen staple, its fruit resembles a yellow-orange olive. In some regions, the fruit pulp is used in traditional confectionery after the toxic seeds are removed.
Supplementation
Dosage: Standard therapeutic dosage is 3 to 10 grams of processed seed (decocted in water). Who should take it: It is best suited for those suffering from chronic cough with difficult expectoration or acid reflux indigestion. Usage: It is rarely eaten raw. It is typically boiled into a herbal soup or taken as a powdered extract found in patent herbal formulas.
⚠️ CRITICAL: Never consume the raw seed. It requires professional processing to reduce toxicity.
