Mako (Inab-us-Sa'lab)

What is Mako (Inab-us-Sa'lab)?

Mako, also called Inab-us-Sa'lab, is the black nightshade plant (Solanum nigrum). It is a single drug in the Persian/Unani system, meaning one plant used on its own. Healers use the leaves, the fresh leaf juice and the fully ripe berries for swelling, liver and stomach complaints, skin sores and poor sleep.

The same plant can poison you if it is used the wrong way. Unripe green berries and raw leaves carry solanine (a natural plant poison). Serious poisonings have been reported, including deaths in young children who ate the green berries.

Mako has a long and wide traditional record, but long use is not proof that it works. No well-designed human trials back its main uses. That single point applies to every section below and is not repeated there.

How does Mako (Inab-us-Sa'lab) work?

Honestly, nobody has shown how Mako works in people. The ideas below come from old texts and from laboratory work, not from human trials.

Unani texts class Mako as cold and dry. On that reasoning it was used to cool "hot" swellings, calm an irritated liver and help the body pass more urine.

Laboratory and animal studies report that extracts can reduce inflammation (swelling and irritation) and protect rodent liver cells from chemical damage. Test-tube work also reports effects on cancer cell lines. None of this tells you what a dose does in a human body.

What forms does Mako (Inab-us-Sa'lab) come in?

Mako is sold and used in a few simple forms. Strength is not standardised, so two products can differ widely.

Fresh leaf juice is the classic Unani form. The leaves are crushed and the juice strained.

Dried leaf and stem are boiled into a decoction (a strong tea made by simmering). Powdered dried herb also appears in mixed Unani formulas.

Ripe berries, dark purple or black and fully soft, are eaten in some regions. Green berries are never used as food.

Ointments and pastes made from the leaves are applied to the skin. Some Ayurvedic and Chinese products use the same plant under other names.

Where it comes from:

Mako appears in Persian and Arabic medical writing from the early medieval period, including the works of Avicenna. It is a long-standing single drug in Unani practice.

The same plant is used as Kakamachi in Ayurveda and as Long Kui in Chinese herbal medicine. It is also eaten as a cooked leafy vegetable across parts of Africa and South Asia after boiling and draining.

What does Mako (Inab-us-Sa'lab) help with?

• Liver complaints and jaundice (yellow skin and eyes): This is the best-known traditional use. Unani texts use the leaf juice for a "hot" liver and for jaundice. The research is animal work. In rats given liver-damaging chemicals, extracts lowered liver enzyme levels. No human trial has tested Mako for liver disease. Jaundice always needs a doctor first.
• Swelling and fluid build-up: Traditional healers use Mako to make you pass more urine and to reduce puffy legs and belly swelling. There is no human evidence for this. Fluid build-up can be a sign of heart, kidney or liver failure, so it needs a proper diagnosis rather than a herb.
• Skin sores, boils and eczema (itchy, inflamed skin): Crushed leaf paste on the skin is a common traditional use across Unani, Ayurvedic and folk practice. Laboratory work shows anti-inflammatory activity in cell and animal models. Human skin trials are lacking. Broken skin absorbs more, so do not spread it over large raw areas.
• Poor sleep: Old texts describe Mako as calming and mildly sleep-inducing. No trial supports this. Any drowsiness you feel may come from the plant's alkaloids, which are also what makes it toxic in larger amounts. Drowsiness here is not a sign of a safe dose.
• Mouth and throat ulcers: A cooled decoction is used traditionally as a mouth rinse for sore gums and mouth ulcers. There is no clinical evidence for this use. Do not swallow the rinse. Ulcers that last more than three weeks need a doctor or dentist.
• Stomach upset and poor appetite: Unani practice uses small amounts of the cooked leaf for a sluggish stomach. No human study supports it. The plant can itself cause nausea, vomiting and cramps, which makes this use hard to judge at home.

What are the side effects of Mako (Inab-us-Sa'lab)?

• Nausea and vomiting
• Stomach cramps and diarrhoea
• Dry mouth and blurred vision
• Drowsiness and confusion
• Headache and dizziness
• Fast or irregular heartbeat
• Passing more urine than usual
• Skin rash or irritation where the paste is applied
• Seizures (fits) in severe poisoning
• Breathing trouble and collapse in severe poisoning

Good to know:

Mild stomach upset is the most common problem. Serious poisoning is rare with careful use but is very real with the wrong plant part.

Unripe green berries and raw leaves cause solanine poisoning. Children have died after eating them. Signs start with vomiting and belly pain and can move on to confusion, fits and breathing trouble.

Treat any of the severe signs as an emergency, not as a side effect to wait out.

Options to discuss with a clinician

For every one of these problems there are routes with far better evidence behind them — and each one starts as a conversation with a doctor, pharmacist or qualified herbalist rather than a straight swap at home.

- **Liver complaints or jaundice (yellow skin and eyes):** this is a red-flag sign, not a symptom to self-treat. A doctor can arrange blood tests and scans to find the cause, which changes what helps entirely. - **Mouth and throat ulcers:** a pharmacist can look at persistent ulcers and point to standard soothing or protective treatments; anything lasting more than three weeks needs a doctor's eyes on it. - **Poor sleep:** ask a clinician about sleep assessment and talking-therapy approaches for insomnia, which have the strongest evidence of anything in this area, and about whether another condition is keeping you awake. - **Skin sores, boils and eczema (itchy, inflamed skin):** a GP or pharmacist can tell infection from inflammation — the two need opposite treatments — and advise from there. - **Stomach upset and poor appetite:** worth raising with a doctor, since unexplained appetite loss needs investigating rather than masking. - **Swelling and fluid build-up:** this can signal heart, kidney or liver problems and warrants prompt medical assessment.

If you want a traditional approach, a registered herbalist can discuss gentler, better-characterised options with you.
