Across the lush mountains of Japan, a unique bamboo species known as Sasa—often referred to as Kumaizasa—has quietly supported health and well-being for centuries. The health benefits of Sasa Bamboo are mentioned in the Classic of the Materia Medica (Shennong’s Herbal Classic), a book written between 206 BC and 220 AD, which serves as a foundational classic in Chinese medicine.
Widely used in traditional Japanese herbalism, Sasa bamboo leaf extract is now gaining renewed attention as a natural botanical ingredient that seamlessly fits into modern wellness lifestyles.
While Japanese consumers have long appreciated Sasa's role in oral care, digestive health, general vitality, and as a pet and animal health ingredient, Sasa bamboo leaf extract remains relatively new among American shoppers.
In the United States, another bamboo leaf extract, derived from Bambusa vulgaris, is consumed in various formats, reflecting its growing popularity as a natural wellness ingredient. Most commonly, it is available as a dietary supplement in capsule or powder form, often standardized for silica content to support the health of hair, skin, nails, and bones. Liquid bamboo leaf extracts are also on the market, typically used as tinctures or added to beverages. These provide a rich source of antioxidants and vitamins B2, B12, C, and K.
Additionally, bamboo extract is widely used in cosmetic and skincare products, contributing to oil control, skin hydration, and improved elasticity due to its anti-inflammatory and antioxidant properties.
This diverse use across the supplement, beverage, and personal care industries reflects growing American interest in natural, plant-based, multifunctional health ingredients.
With the launch of SBRx-10 by Superfood Science, natural product enthusiasts can now experience a clean, plant-based extract rooted in centuries of tradition and supported by modern science.
What Is Sasa Bamboo Leaf Extract?
Sasa bamboo includes several broadleaf bamboo species native to Japan, such as Sasa veitchii, Sasa senanensis, and Sasa albomarginata. Unlike tall bamboo used in construction, Sasa species grow closer to the ground and are prized for their soft, aromatic leaves.
Long before modern refrigeration, Japanese households relied on Sasa bamboo leaves to naturally preserve food. These broad, aromatic leaves were traditionally used to wrap items such as fish, sushi, pickled vegetables, and rice cakes like *sasa-dango*.
Thanks to their natural antibacterial and deodorizing properties, Sasa leaves help inhibit the growth of spoilage-causing bacteria and reduce unwanted odors, particularly in fish and fermented foods (Sakagami & Tomomura, 2018; Yoshida et al., 2020).
Their structure allowed them to retain moisture while permitting airflow, creating a balance that kept foods fresh longer without becoming soggy or moldy. It made them especially useful for portable meals, including rice wrapped in Sasa leaves carried by warriors during the Warring States period (MAFF, 2023a).
Beyond function, sasa leaves served as eco-friendly, biodegradable food wrappers, often used in bento boxes, ceremonial offerings, and local festival foods. Traditional dishes like sasazushi in Niigata and sasa-dango in regional celebrations continue to honor this practice today (MAFF, 2023b; MAFF, 2023c).
This historical use highlights the preservative value of sasa leaves and their deep cultural roots in everyday Japanese life, a legacy that continues today in culinary and wellness applications.
These leaves have also been steeped into teas or included in Kampo formulas to promote wellness.
The modern extract used in SBRx-10 is produced through a multistep hot water extraction process under high temperatures and pressures. This method concentrates the leaf’s valuable polyphenols, chlorophyll, and polysaccharides, resulting in a potent, caffeine-free botanical that supports daily well-being.

Key Benefits of SBRx-10 for Everyday Wellness
1. Rich in Natural Antioxidants
Scientific analyses have shown that Sasa leaf extract contains active compounds like tricin, p-coumaric acid, ferulic acid, and caffeic acid. These molecules help reduce oxidative stress in cells, a key factor in supporting healthy aging and overall vitality (Kojima et al., 2022).
2. Supports a Balanced Inflammatory Response
In laboratory studies, extracts of Sasa albomarginata have been shown to moderate the expression of inflammatory markers such as IL-6 and nitric oxide in immune cells. While these results are preclinical, they indicate a potential for Sasa extract to support a healthy inflammatory balance when consumed regularly (Kojima et al., 2022).
3. Traditionally Used for Immune Health
In Japanese Kampo practice, Sasa bamboo is often used to promote resilience and vigor. Studies on hot-water extracts have observed the activation of macrophages and natural killer (NK) cells in animal models, suggesting support for the body’s natural defense mechanisms (Seki et al., 2008; 2010).
4. Gentle Support for Oral and Digestive Health
Sasa leaf extract is widely used in Japan in mouthwashes and toothpaste products for oral freshness. It has also been studied for its mild effects on digestive comfort, partly due to its plant polysaccharides and soothing properties (Sakagami & Tomomura, 2018).
5. Skin and Beauty Applications
Thanks to their moisturizing and calming properties, topical preparations with Sasa extract are becoming popular in Japan and Korea. The extract's antioxidants help reduce the impact of environmental stressors on the skin.
The Expanding Market for Sasa Bamboo Products
While the global bamboo market is growing, Japan remains a key innovator in specialty applications like food-grade Sasa leaf, wellness products, and herbal cosmetics. According to recent market research, Japan’s bamboo industry was valued at approximately USD 1.88 billion in 2023 and is projected to grow to USD 2.54 billion by 2032. Much of this growth is fueled by consumer interest in sustainability and natural health products.
Although the exact figures for Sasa bamboo are limited, it plays a distinct role in the industry due to its applications in herbal medicine, food wrapping, and natural hygiene products. Ongoing R&D efforts in Japan have refined extraction methods—like the “vigorous extraction” process used in SBRx-10—to concentrate its bioactive components and improve consistency in supplements.
