Yes, there are several protein-rich natural herbs that you can consume. Here are a few:

1. Spirulina: This blue-green algae is a complete protein, meaning it contains all nine essential amino acids [1]. It is also rich in other nutrients like B-vitamins, iron, and calcium.

2. Hemp Seeds: Hemp seeds are a great source of plant-based protein. They contain all nine essential amino acids and are especially high in arginine and glutamic acid [2].

3. Moringa: Also known as the drumstick tree, moringa leaves are packed with protein. They contain all nine essential amino acids and are also rich in vitamins A, C, and E [3].

4. Parsley: This herb is not only rich in vitamins but also contains a good amount of protein. It is particularly high in the amino acid tryptophan [4].

5. Coriander: Also known as cilantro, coriander is a good source of protein. It is rich in arginine, lysine, and tryptophan [5].

6. Basil: This herb is not only flavorful but also a good source of protein. It contains all nine essential amino acids [6].

Remember, while these herbs are rich in protein, they should not replace a balanced diet. It's always best to consult with a healthcare provider or a nutritionist for personalized dietary advice.
