Lessertia frutescens, more commonly known as Cancer Bush or Sutherlandia, is a hardy, indigenous South African shrub revered for centuries by Khoisan and traditional healers. This perennial, with its vibrant red-orange pea-like flowers and balloon-shaped seed pods, has a rich ethnobotanical history. It is celebrated not just for its beauty but for its powerful place in African herbal medicine.
💊 Medicinal Benefits
Traditionally used to support immune function and relieve stress, Cancer Bush is also believed to ease symptoms of chronic fatigue, stomach ailments, viral infections, and even cancer. It contains L-canavanine, pinitol, and GABA, compounds known for anti-inflammatory and adaptogenic effects. While clinical studies are ongoing, anecdotal evidence supports its use for:
- Immune boosting
- Appetite stimulation (especially in HIV and cancer patients)
- Anxiety and depression relief
Disclaimer: Always consult a healthcare professional before use. High doses may cause nausea or gastrointestinal upset.
📅 When to Plant in South Africa
Plant Cancer Bush seeds in early to mid-spring, ideally between September and November, for optimal germination and root development before winter. Transplant seedlings after 6–8 weeks, once they reach 10–15 cm in height.
🏡 Where to Plant
Choose a warm, sunny area in your garden. Cancer Bush does best planted directly in the ground, particularly in climates that mimic its natural arid habitat. It thrives in dry, rocky regions and open plains.
🌞 Soil, Water & Sunlight Requirements
✅ Soil
Well-draining, sandy or loamy soil with a neutral to slightly alkaline pH. Avoid clay-heavy, water-retentive soils.
✅ Sunlight
Requires full sun (at least 6–8 hours daily). Shade may reduce flowering and slow growth.
✅ Water
Water sparingly. Once established, Cancer Bush is drought-tolerant. Water only when the topsoil is dry.
✅ Fertilize
Use a balanced organic fertilizer once a month during the growing season. Avoid overfeeding.
✅ Spacing
Plant 30–50 cm apart to ensure good air circulation and prevent fungal issues.
✅ Seeds Germinate
Seeds germinate in 2–4 weeks. Scarify seeds slightly or soak overnight in warm water to improve germination rates.
✅ Transplanting
Transplant after 6–8 weeks or when the seedlings are at least 10 cm tall. Handle roots gently.
✅ Maturity Height
Reaches 50 cm to 1.5 meters tall. May become woody with age and benefit from light pruning.
🍓 Flowers & Fruit
Cancer Bush produces bright scarlet to deep orange flowers in spring and summer, followed by distinctive inflated pods. These balloon-like seed pods give rise to the nickname “Balloon Pea.”
🌼 Companion Plants
Pairs well with fellow drought-tolerant herbs such as:
- Lavender (natural pest deterrent)
- Thyme (improves soil aeration)
- Rosemary (enhances pollination)
🐛 Common Pests
Watch for:
- Aphids
- Red spider mites
Control with neem oil spray or introduce natural predators like ladybugs.
🧺 Harvesting
Harvest leaves and stems in the second or third year. Cut early in the morning after dew has dried. Allow the plant to regrow naturally.
🫙 Storage
Dry harvested material in a shaded, well-ventilated area. Once fully dried, store in an airtight container away from light and moisture. Dried leaves can last up to 12 months.
🧪 How to Use as Medicine
- Tea:
Steep 1 tsp dried leaves in 1 cup boiling water for 10 minutes. Drink once daily. - Tincture:
Add fresh leaves to 40% alcohol (1:2 ratio) and let sit for 4–6 weeks. Strain and store. Take 10–20 drops daily. - Infused Capsules:
Dried leaf powder can be encapsulated and used under supervision.
Disclaimer: Always begin with small doses. Not recommended during pregnancy or for children without medical advice.
🎉 Fun Fact
Sutherlandia was one of the earliest plants used by traditional healers to treat “wasting diseases”—long before modern medicine recognized the effects of immune-related disorders like cancer and HIV/AIDS.
⚠️ Caution
Avoid high doses. Potential side effects include nausea and dry mouth. Not suitable for use in pregnancy, breastfeeding, or in conjunction with pharmaceutical antidepressants or chemotherapy without medical supervision.
