Hello: Authentic hairy crabs refer to those produced in Yangcheng Lake, Jiangsu Province.
The crabs are particularly rich and fatty in the autumn, containing vitamin A, fats, proteins, and small amounts of calcium, phosphorus, and iron.
Compared to common fish and shrimp, they are not particularly special, and their medical uses are limited.
However, according to traditional Chinese medicine, crab meat is considered very cold and is not suitable for patients with gastric diseases, inflammatory or purulent surgical conditions, frequent abdominal pain and diarrhea, or those prone to wind-dampness syndromes.
Generally, after enjoying the delicious crab meat, drinking a cup of ginger tea can help dispel the coldness.

More Info


Hairy crabs, or "Dazha crabs," are a seasonal delicacy, particularly popular in East Asia, especially during the autumn months. These crabs are not only a culinary delight but also offer various nutritional benefits that can contribute positively to your overall health.

Firstly, hairy crabs are an excellent source of high-quality protein. Protein is essential for the body as it helps in the repair and growth of tissues, including hair. Consuming adequate protein can support hair health, making it stronger and potentially reducing hair loss. In addition to protein, hairy crabs are rich in essential amino acids, which are the building blocks of proteins and play a crucial role in various bodily functions.

Moreover, hairy crabs are a good source of omega-3 fatty acids, which are known for their anti-inflammatory properties. Omega-3s can help improve scalp health by reducing inflammation and promoting blood circulation, which is vital for healthy hair growth. A well-nourished scalp can lead to stronger hair follicles and, consequently, healthier hair.

In addition to protein and omega-3 fatty acids, hairy crabs are also rich in vitamins and minerals. They contain significant amounts of vitamin B12, which is essential for the production of red blood cells and the maintenance of the nervous system. Vitamin B12 deficiency can lead to hair loss, so including hairy crabs in your diet can help mitigate this risk. Furthermore, they are a good source of zinc, which plays a critical role in hair tissue growth and repair. Zinc deficiency has been linked to hair loss, making it important to ensure adequate intake of this mineral.

Hairy crabs also provide selenium, a trace mineral that acts as an antioxidant. Antioxidants help combat oxidative stress, which can damage hair follicles and lead to hair loss. By including foods rich in selenium, such as hairy crabs, you can help protect your hair from damage caused by free radicals.

However, it is essential to consume hairy crabs in moderation, as they can be high in cholesterol and sodium. If you have any underlying health conditions, such as high cholesterol or hypertension, it is advisable to consult with a healthcare professional before incorporating them into your diet.

In conclusion, hairy crabs can be a nutritious addition to your diet during their season. They provide high-quality protein, essential fatty acids, vitamins, and minerals that can contribute to overall health and potentially improve hair health. As with any food, balance and moderation are key. Enjoying hairy crabs as part of a varied and balanced diet can help you reap their nutritional benefits while maintaining your health.
