Ilex tectonica has a wide distribution and apparently has a stable population though it is not currently known in many locations. The species is also experiencing a reduction in the habitat available to it. The extend of the known range and also number of sites in which it is found is likely to increase as more collections or more revisions of herbarium specimens are made. It probably occurs in more than 10 locations. The plant is currently classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2021)[

The berries are usually the part of the plant most likely to be toxic, though the degree of toxicity is usually low. Their bitter flavour usually prevents a person eating more than one or two, but even a small handful of the fruit eaten by a healthy adult is unlikely to cause more than feelings of nausea that can lead on to vomiting and diarrhoea[

The compounds in the leaves are particularly interesting. The leaves of many Ilex species around the world are commonly used to make health-promoting teas that, when drunk on a regular basis, help to regulate bodily functions and can reduce the risk of heart disease, lower blood-cholesterol levels etc (See Ilex paraguariensis or Ilex kaushue for examples)[

]. Even these teas, however, if taken in very concentrated doses, can act as a laxative or cause vomiting. Indeed, several species are used by traditional peoples to induce vomiting as a means of purifying the body (see Ilex guayusa or Ilex vomitoria for examples)
