Beliefs, customs, taboos and traditional practices

What makes a practice helpful or dangerous is not whether it is traditional, but its method, dose, route, sterility and timing — and the condition of the person receiving it. Take the same intervention apart. Uvulectomy, the cutting of the uvula in infancy, is performed as a cure for repeated throat problems; the mechanism of harm is immediate bleeding from the rich blood supply of the soft palate, pain that stops the infant feeding, dehydration, and, when the instrument is not sterile, infection including tetanus. Scarification makes small cuts to introduce medicines or marks; the mechanism of harm is the shared blade, which transmits blood-borne viruses such as hepatitis B, hepatitis C and HIV, together with the local infection that follows. A traditional bone setter achieves good results for many closed fractures, and the danger concentrates in open fractures, fractures of the thigh, and injury to nerves or blood vessels — where delay turns a treatable injury into malunion (a bone that heals in the wrong position), chronic pain or amputation. Enemas given for constipation or fever can perforate the bowel and cause severe electrolyte loss in a small child. A pregnancy food taboo that removes eggs, meat and fish is not dangerous in one meal; it becomes harmful through a cumulative deficiency of protein, iron and folate over months, raising the risk of anaemia and low birthweight. The nursing lesson is to ask about the preparation, the dose, the route, who performed it and when, then examine the patient rather than the label. Harm is a mechanism, not a category. Report suspected harm from a herbal product through the national pharmacovigilance system, and record the plant name in the local language, because an unnamed exposure cannot be investigated later.

The interaction question is pharmacokinetic before it is cultural. A herbal preparation changes a prescribed drug in four main ways. It may speed up the liver enzymes that destroy the drug — induction of cytochrome P450, especially CYP3A4 — so that blood levels fall and treatment fails; St John’s wort, or millepertuis, is the best-documented example, lowering ciclosporin, some antiretrovirals, oral contraceptives and warfarin. It may block the same enzymes, so levels rise and toxicity appears. It may change transport proteins such as P-glycoprotein, which pumps drugs out of cells and out of the gut. Or it may add its own effect to the drug: garlic, ginkgo and some anti-inflammatory plants increase bleeding risk on top of warfarin or aspirin; liquorice lowers potassium and can make digoxin toxic; preparations with diuretic or laxative action disturb fluid and electrolytes. Two practical traps make this hard. First, patients often do not call a daily herbal tea a medicine, so the direct question — what do you take? — gets a no, while the specific one — what do you drink or chew for your health? — gets the truth. Second, the interaction is not prevented by separating the doses in time: enzyme induction lasts for days and continues whatever the timetable. The nurse’s actions are therefore concrete. Ask about every preparation, including market medicines and leftovers. Write the local name and its purpose in the file. Check the interaction for the drugs this patient actually takes. Monitor the sign that would change — blood pressure, glucose, INR (the clotting time used to monitor warfarin), drug levels. Never tell a patient to stop a prescribed drug on your own, and never let a suspected interaction go unreported.

Changing a practice is a communication problem before it is an educational one. Motivational interviewing, developed by William Miller and Stephen Rollnick, works from the finding that argument produces resistance: the more forcefully a nurse lists reasons to stop, the more the family defends the practice, because defending it also defends identity and authority. The method replaces persuasion with evocation — asking what the family already worries about, and letting them state the reason for change in their own words. Prochaska and DiClemente’s stages-of-change model explains why timing matters: a family that has not yet considered a change is in pre-contemplation, and information given then is heard as an attack, whereas the same information is accepted once the family is already doubting. The cross-cultural interview framework known as LEARN — Listen, Explain, Acknowledge, Recommend, Negotiate — puts the order right: hear the practice and its purpose, explain your concern in plain words, acknowledge what the practice does well, recommend a specific safer option, and negotiate rather than impose. Melanie Tervalon and Jann Murray-García named cultural humility as the alternative to cultural competence used as a checklist: the nurse cannot master every tradition, but she can remain a learner, ask, and accept that the family is the expert on its own life. Harm reduction supplies the practical rule: if the family will not abandon a practice, reduce its frequency, its dose or its risk — a clean blade instead of a shared one, a delay until after treatment, a substitute that keeps the meaning. Finally, negotiate with power as it exists: in many households the decision belongs to a grandmother, an uncle or a husband, so convincing only the patient produces an agreement that cannot be kept. Record what was agreed, and check it at the next visit.
