Spots that appear on the skin, which can look like henna stains, are usually nothing more than a reaction linked to the colon or the liver, and sometimes even the kidneys.
You should therefore drink chamomile herbal teas or take purgatives such as senna in a small dose or fennel seed.
To cleanse the intestines and the colon, it is also recommended to drink juices, as well as black seed.
Be careful not to link the appearance of these spots to false beliefs, at the risk of making yourself sick for nothing, when scientific evidence is there to show us that the cause comes from something inside the body.
What the science says: natural skin care
What published research says about the remedies mentioned above, for context—the studies address material causes, while healing belongs to Allah.
Natural skin care
Aloe vera promotes healing and soothes the skin according to a review of clinical trials (Iran J Med Sci, 2019) (Plast Reconstr Surg, 2018); in eczema, daily moisturizing with emollients is the foundation of treatment (Int J Dermatol, 2025) and the skin microbiome plays a central role (J Eur Acad Dermatol Venereol, 2023). Olive oil, black seed oil, honey, and shea butter are the emollients of tradition. Precaution: test any new product on a small area for 24 hours; a lesion that spreads, oozes, or becomes infected calls for a doctor.
