conjunctivitis

flower, decoction, compresses^1-2,21

For conjunctivitis:

Prepare an infusion with 1/2 liter (2 cups) of boiling water and 3-4 white flowers. Cover pot, leave to cool down for 5-10 minutes, and filter. Apply the infusion, with a cotton compress, on the affected eye for 5-10 minutes, repeat 2-3 times a day.

According to published and other information:

Use for conjunctivitis is classified as REC, based on the significant traditional use documented in the TRAMIL surveys, on toxicity studies and on available published scientific information.

Strict hygiene measures should be observed in order to avoid contamination or additional infection and to avoid contact with conjunctiva-irritating substances.

Should there be a notable worsening of the patient’s condition, or should conjunctivitis last more than 3 days, medical attention should be sought for.

Do not ingest any part of the plant due to toxicity risk.

TRAMIL Research¹⁷

The aqueous extracts (decoction, 20 minutes) from the white flower (20%), fresh or dried, were left to cool down at room temperature and strained. In the Draize ophthalmic irritability model, the extracts were topically applied (0.1 mL) to the bottom of the conjuctival sac of 6 male New Zealand rabbits, and caused no irritation in the normal eye.

The flower decoction administered orally to rat reduced the size and weight of fetuses¹⁸.

The hydroalcoholic extract (95%) from the leaf administered orally (75 mg/kg) resulted in a general toxic effect in male rat¹⁹.

The ingestion of the entire plant showed toxic effects in human²⁰.

There is no available information documenting the safety of medicinal use in children or in pregnant or during breast feeding.

The flower contains: alkaloids: zeatin³; indole alkaloids: ajmalicine, tetrahydroalstonine⁴, aparicine⁵, carosine, catharicine, leurocristine⁶, coronaridine⁷, catharanthine, serpentine, vindoline⁸; and flavonoids: hirsutidine, malvidin⁹.

The aerial parts contain most of the above mentioned alkaloids as well as: vinblastine and vincrystine¹⁰, and the leaf, alkaloids: catharanthine and vindoline¹¹.

TRAMIL Research¹⁷

The decoction of the fresh white flower (20%), administered in the bottom of the conjunctival sac (0.1 mL) of rabbits, significantly diminished the discrete ocular secretion induced by prior rubbing of the eye for 60 seconds. The extract from the dried flower was less effective.

The aqueous extract from the entire plant was weakly active as an antibacterial agent against Escherichia coli, Salmonella paratyphi B, Staphylococcus aureus, Vibrio cholera and inactive against Salmonella paratyphi A, S. typhosa and Shigella flexneri¹².

The benzene extract from the dried flower and leaf (5%) was active as an antibacterial against Proteus spp., Pseudomonas spp., some Shigella spp., Staphylococcus spp, and inactive against Salmonella spp. and Shigella paradysenteriae¹³.

An extract from the dried flower was weakly active as an antifungal against Trichophyton rubrum, by protease inhibition¹⁴.

The hydroalcoholic extract (95%) from the dried aerial parts in a (50%) ratio was active as an antifungal against Neurospora crassa, unlike the acetone and aqueous extracts, which showed no antifungal activity¹⁵.

The petroleum ether extract from the flower, leaf, seed and stem showed larvicidal activity against Anopheles stephensi at 100 ppm; against Aedes aegypti at 50 ppm, and against Culex quinquefasciatus at 80 ppm¹⁶.
