Moringa is likely safe when taken orally according to the suggested dosage, but its root and extracts can lead to paralysis and death, according to WebMD. Its roots, barks and flowers may be unsafe for pregnant and lactating women, as these parts contain chemicals that can cause uterus contraction or miscarriage.
Moringa contains antioxidants that provide protection against cell damage, according to WebMD. It is also a source of vitamins, proteins and minerals. The supplement is typically taken orally to improve asthma, anemia and arthritis. A study suggested that oral intake of 3 grams of moringa twice a day for three weeks alleviated the symptoms of asthma and also improved asthma attacks in adults. Some people also use moringa as a topical treatment for athlete’s foot, dandruff, warts and skin infections.
To use moringa safely, an individual may take a maximum dosage of 6 grams per day for three weeks, says WebMD. The plant’s leaves, seeds and fruits can be safely eaten as food.
While some women use moringa for breast milk production, health experts recommend that nursing women should avoid the supplement, as there is no conclusive evidence regarding the plant’s safety for a nursing infant, notes WebMD. Anyone who plans to use moringa should consult a health care provider, as the correct dosage varies depending on a person's age and health condition.
